When should you get high index lenses?
High index lenses are usually considered for myopic patients. This means people who are nearsighted which means they can't see clearly at distance. Around -3.00 or -4.00 providers will consider using a high index lens to reduce the thickness. If you have a prescription is higher than a plus or minus 5.00 we strongly recommend getting a high index lens.
Are there contact lenses for computer use?
Yes, there are contact lenses specifically designed for computer use. These contact lenses, also known as computer glasses or computer contacts, are designed to reduce eye strain and fatigue caused by prolonged computer use. They work by filtering out blue light, which is a type of light that is emitted by computer screens and other electronic devices. Blue light has been shown to cause eye strain and fatigue, and it can also disrupt the body's natural sleep-wake cycle.
If you experience eye strain or fatigue when using a computer, it may be worth considering computer contact lenses. However, it is important to consult with an eye doctor before trying these lenses, as they will be able to determine whether they are appropriate for you and provide guidance on lens care and handling.

Should I purchase contact lenses online?
In general, it is a good idea to purchase contact lenses from a reputable source, such as a licensed eye care doctor. This can help ensure that you are getting a high-quality product that is appropriate for your vision needs and that you are following proper lens care and handling techniques to maintain the health and comfort of your eyes. If you have any concerns about purchasing contact lenses online, it is a good idea to consult with an eye doctor.

Can you shower with contacts?
It is generally not recommended to shower with contact lenses in, as water can contain bacteria and other contaminants that can cause eye infections. In addition, water can cause contact lenses to become loose or move around on the eye, which can be uncomfortable or potentially dangerous. If you need to remove your contact lenses while showering or washing your face, it is important to follow proper lens removal and handling techniques to avoid damaging the lenses or contaminating them with bacteria.

How do I get rid of spots on my contact lenses?
To get rid of spots on your contact lenses, you should first clean your lenses thoroughly using a contact lens cleaning solution. Rub the lenses gently with your fingers, then rinse them thoroughly with the cleaning solution. After cleaning your lenses, disinfect them using a disinfecting solution or soaking them overnight in a disinfecting solution. It is also a good idea to check the expiration date of your cleaning and disinfecting solutions to make sure they are not expired, as using expired solutions can cause spots to appear on your lenses. If you have been using the same contact lens case for a long time, consider replacing it, as contact lens cases can accumulate bacteria over time. If these steps do not help to get rid of the spots on your contact lenses, or if you have any concerns about the health of your eyes, it is important to consult with an eye doctor.

Contacts or glasses: which are best for you?
The decision of whether to wear glasses or contact lenses is a personal one that depends on your individual needs and preferences. Both glasses and contact lenses can be effective at correcting vision, and the best option for you will depend on your specific vision needs and lifestyle.
Glasses are a convenient and low-maintenance option for vision correction. They are easy to use and do not require any special handling or care. They also do not come into direct contact with the eye, which may be a benefit for people with allergies or sensitive eyes.
Contact lenses, on the other hand, provide a wider field of vision than glasses because there are no frames obstructing the view. They also do not fog up or get dirty as easily as glasses and do not slip down the nose or get knocked off as easily as glasses. However, they do require more maintenance and care than glasses, as they need to be cleaned and replaced regularly to maintain good eye health.

Can you wear contact lenses after LASIK or other refractive surgery?
It is generally recommended to wait at least three to six months after LASIK or other refractive surgery before wearing contact lenses. This is because the shape of the cornea may continue to change during the healing process, and contact lenses may not fit properly or may cause discomfort until the healing is complete.
If you are cleared to wear contact lenses, it is important to follow your eye care professional's instructions for lens care and handling to reduce the risk of infection or other complications.

Can I buy contact lenses without a prescription?
In most cases, you cannot buy contact lenses without a prescription. Contact lenses are classified as medical devices, and it is generally illegal to sell or distribute them without a prescription.
To get a prescription for contact lenses, you will need to have an eye exam with an optometrist or ophthalmologist. During the exam, the eye doctor will assess your visual acuity, eye health, and the fit of the contact lenses to determine the appropriate prescription. They will then write a prescription for the contact lenses, which you can use to purchase them from a licensed retailer.

Can contacts get lost in your eye?
It is possible for a contact lens to get lost in your eye, but it is generally not a serious or life-threatening problem. When you wear contact lenses, the lens sits on the front surface of your eye, also known as the cornea. If a contact lens becomes dislodged from the cornea, it can move to the inside corner of the eye near the nose, or under the upper eyelid. In most cases, the contact lens can be easily retrieved by the eye doctor or a trained eye care professional.
If you are wearing contact lenses and notice that one has become lost in your eye, you should not try to remove it yourself. Instead, you should contact our eye doctor. They will be able to safely remove the contact lens and check to make sure that your eye is healthy. If you are unable to remove the contact lens or are experiencing any other problems with your eyes, you should seek medical attention immediately.

Are contacts hard to put in?
Most people find that after a little of a learning curve, contact lenses are easy to put in and take out. The difficulty of putting in contact lenses can vary depending on the individual and the type of contact lenses being used.
Soft contact lenses are generally easier to insert and remove than hard or rigid gas-permeable (RGP) lenses, as they are made of a flexible, water-containing material that conforms to the shape of the eye. They can be rolled or folded to make them easier to handle, and they can be inserted directly into the eye without the need for special techniques.
RGP lenses are made of a hard, gas-permeable material that allows oxygen to pass through to the eye. They are more durable and provide better vision correction than soft lenses, but may take longer to adjust to and may be less comfortable for some people. RGP lenses can be more difficult to insert and remove, as they are firmer and do not conform to the shape of the eye as easily. Special techniques, such as pinching the lens with the thumb and index finger or using a lens inserter or remover tool, may be needed to handle and insert RGP lenses.
It is important to follow the prescribed wearing and care instructions provided by the optometrist and contact lens technician during your contact lens fitting to ensure the health and comfort of the eyes. This may include using specific cleaning and disinfecting solutions and replacing the lenses according to the prescribed schedule. If you have difficulty inserting or removing your contact lenses, it is a good idea to ask for assistance or additional instruction from our eye care professionals. With practice, most people are able to become comfortable with inserting and removing their contact lenses.

Are contact lenses safe for kids?
Contact lenses are increasingly prescribed to children and are generally seen as a safe and effective option for correcting vision in children, as long as they are prescribed and used properly. Children who are interested in wearing contact lenses should be evaluated by an optometrist to determine if they are a good candidate for contacts and to determine the best type of contact lenses for their needs. One of the primary uses for contact lenses in kids ages 8-18 is to slow down progression of childhood myopia. This intervention includes specialty contact lenses such as MiSight, which are FDA approved contact lenses to slow down the progression of your child's prescription.
There are several factors to consider when deciding whether contact lenses are suitable for a child. These include the child's age, maturity level, and ability to follow the prescribed wearing and care instructions. Children should be able to demonstrate good hygiene habits and be able to handle and care for their lenses properly in order to reduce the risk of complications.

We are proud to be a leading provider of advanced eye care and contact lens services for patients from CITY, SECONDARY1, SECONDARY2, and SECONDARY3.
Is anti reflective coating necessary for glasses?
While not necessary, Anti-glare treatments are generally recommended for glasses and for good reason. Anti-glare or anti-reflective coatings come with a bevy of benefits. They eliminate glare from incoming light which provides for more crisp vision. Also, most anti-glares come with secondary benefits such as scratch and water resistance which helps to keep the surface clean and clear.
What is prism lenses?
Prism lenses are lenses that shift the focal point in a certain direction but a unit called diopters. What this mean is, depending on the diopters of prism, a lens will move the "image" over that much. Prisms have no refractive quality, meaning they don't help you see clearly like other lenses typically do. Instead they shift images in a certain direction so help our eyes pair images together into a single image in your mind.
What do prisms in glasses do?
Prisms in glasses typically shift light, which we perceive as an image, in a general direction, For instance prisms are usually prescribed in both lenses and will move the image in a direction that makes it easier for the patient to make the images into a single one.
Are high index lenses worth it?
It's really relative to what the actual prescription is and also the preference of the patient. If the Rx is approaching a high value such as -4.00 and above then it's generally time to consider high index. Also, they are more aesthetically appealing than other materials, such as polycarbonate, which would be thicker and more unseemly given the same Rx. Also, high index has a higher abbe value and what this means is light refracts more cleanly through the lens making the vision clearer. All in all, higher index lenses are worth it if applicable.
How thick will my glasses be? What factors impact the thickness of my glasses?
A handful of factors impact lens thickness. Thickness can occur in two places on a lens: center and edge. The power of the lens will determine where thickness is distributed. For instance, people with plus lenses will have their thickness in the middle. People with minus powered lenses will have edge thickness. The biggest contributing factor to either power lens for thickness in the sphere or main power of the lens. The higher it is, the thicker lenses generally are relative to their power. High plus thick center and high minus thick edge. Prisms can also add thickness to a given edge if they're a high enough diopter.
What are the different types of bifocal lenses?
There are a few different ones so I'll hit off on the most commonly used. The flat tops are the most commonly used. They have a straight hard line that separates the distance from the reading portion. Flat top 28 - Bifocal width will be 28mm Flat top 35 - Bifocal width will be 35mm.
There are also rounded bifocal - The bifocal is round instead of the traditional half circle. There is another style called blended bifocal which is less noticeable because it does not stand out as the lined bifocal by eliminating the hard line and introducing a softer, smoother and rounded edge to the reading section.Then we have executive style which is essentially a flat top but with altered measurements that make the reading portion the entirety of the Rx below the line and distance Rx above it.
Lastly we have Double D - Theses lenses have a bifocal on top of the lens and on the bottom
How much thinner are high index lenses?
The answer varies and is dependent on a few factors. Frame measurements, width and length, will contribute to lens thickness as well as the power of the lens. There's no real way to predict with certainty the thinness of a high index lens pre-cut but general rule of thumb is somewhere between 1-3mm thinner compared to lower index material.
What lens coatings should I get on my glasses?
This is another tricky one because there's no one size fits all approach. We have to consider the patient, diagnoses, frame and Rx before we make a determination regarding AR coatings. Generally speaking, with the people who fit into "normal" Rx ranges and diagnoses most AR coatings would suffice. It really depends on usage of the Rx but your standard Super Hydrophobic Anti-Glare coating would be a good place to start for anyone.
Is anti scratch coating necessary for glasses?
Hardly anything is necessary when it comes to lenses, aside for the proper fulfilling of the Rx. However, there are things to be done that can improve the overall optical experience like adding an anti-scratch/anti-reflective coating to your lenses. So, let's make a distinction from the get go to avoid confusion later. All anti-scratch coatings are also anti-reflective or anti-glare but not all anti-reflective coatings have a scratch resistant quality. This is important when deciding on what type of anti-reflective to get on your lenses. Every anti-reflective is constructed differently and some offer just the refractive qualities of an anti-reflective while others incorporate the scratch resistance element as well. While it isn't necessary there are a myriad of benefits to choosing a scratch resistant coating for lenses. Not only do you get the benefits from your standard AR lenses but you'll also get that smoother, hydrophobic, scratch resistance which can contribute to an increase in lens longevity. Meaning, with a little bit of care, you'll get a lot more wear.
Furthermore we strongly recommend getting scratch resistant coatings for children's glasses, because kids will be kids.
Are polycarbonate lenses scratch resistant?
In short, while they do not scratch very easily they are not scratch proof. Polycarbonate lenses are rated as one of the most impact resistant materials for lenses as opposed to plastic or high index but impact resistance doesn't translate to scratch resistance. The highest degree of scratch resistance is typically attained with an anti-glare/anti-scratch coating. These coatings, in their varying levels, offer scratch resistance when placed onto a lens material.
What is blue light protection?
Blue light protection is a coating that is applied to a lens to filter out "harmful" light. There are studies that say too much blue light is harmful to retinal cells and cell health. The jury is still out on the subject but in any event the coating could protect from potentially harmful blue light exposure.
How do I keep my glasses from sliding down my nose?
In short, a good adjustment will typically hold your glasses in place. What this means is the angle of the temple, the part that curves behind the ear, is just right to hold your glasses comfortably. The nose pads are adjusted and angled correctly to compliment the temple adjustment. On occasion, a little more handiwork is needed but generally those two adjustments work for most people.
How do you wear a face mask with glasses?
One of the best ways to wear a mask with glasses to reduce fog and keep the Rx intact depends on the type of mask being worn. Generally, if you can position your glasses just slightly over and past the top of the mask you'll be able to achieve a comfortable and fogless setup. Be careful, too far down your nose changes the Rx and may lead to complications.
What are glasses lenses made of?
Lenses are primarily made out of plastics these days. The plastic or polymers they are made out of can be separated into four categories. We use CR-39, Polycarbonate, Trivex, and Hi-Index. Depending on the Rx, Age of patient, and their needs will determine the lens material that's chosen.
How do I stop my glasses mask from fogging up?
In this day and age this is the question. We can do one of two things or a combination of the two. Position the glasses and mask differently and or use anti-fog spray. The fogging comes from the exhaling of hot air and if the mask isn't positioned properly it'll be funneled right into the space between your glasses and your eyes. In that area it hasn't had enough time to cool, hence the fog. If we increase the size of that space by positioning our glasses over our mask, and not before it, we'll channel the air differently and allow enough space for the hot air to dissipate. Also we can buy anti-frog sprays and apply them to our lenses for added protection. Do your research, find one that works, and use it in conjunction with proper glasses positioning to reduce fogging.
How long does anti reflective (AR) coating last?
This depends on a few factors. AR coatings can last anywhere from six months to seven or more years and here's the breakdown. Just like everything else, there are different companies offering different tiers of AR coatings. Not surprising, the most expensive usually last the longest. Generally, if you keep your A coatings away from chemicals, extreme and prolonged heat exposure, clean appropriately, you can get a long life from them.
What is anti reflective coating on glasses?
Anti-reflective coating is almost just as it sounds. It is a very thin coating that's applied to the lens to help light move more cleanly through the lens. What this means is that the incoming light gets to your retina without bouncing around or heading in other directions. This reduces glare and makes vision a touch sharper. Some anti-glare coatings also have added benefits. Some coatings are also hydrophobic, meaning they repel water. Some also provide added scratch, dirt and dust resistance.
What are computer glasses?
Computer glasses are used to see at an intermediate range, thusly named. They are a composite of the sphere power of an Rx and about half the addition. When combined we'll have a prescription for intermediate or computer glasses that will let us work comfortably at that range.
What lenses help with night driving?
In my experience, there's only one trusted method for increasing visibility at night and that's an anti-glare coating. Some providers suggest using differing tints, such as yellow tints, with an AR coating. Tinted lenses filter out a spectra of light which overall reduces light data that goes into the retina and in low light conditions this can prove dangerous. The most effective and virtually danger free method is an AR coating. As of late, companies have produced specifically formulated AR coatings to reduce glare for night driving. The goal is to reduce diffraction, which is light bouncing around and away from the focal point of the lens, resulting in glare such as halos, without reducing the light coming in that's necessary to see an image. Much like when we see oncoming headlights and they're engulfed in a ring of light. An AR coating helps reduce this ultimately let us see more of what's important, the road.
What are daily disposable contact lenses?
Daily disposable contact lenses are single-use contacts that are discarded after one day’s use. With this design you open up a fresh new pack every day. Daily disposable contacts are more convenient because there is no lens cleaning required and they do not need to be stored in a solution or case. Daily disposable contact lenses are also healthier on the eyes since they are less prone to lens deposits accumulating and there is less of a chance to develop contact lens related eye infections. Daily disposable contacts are also sometimes found to feel more comfortable due to the thinner nature of the lens.
What lenses are best for presbyopia?
This is really up to what your Doctor recommends after your examination. They will consider not only acuities but how your eyes function as a team. This is important because not all eyes can use the varied options of lenses for presbyopia. One of the better options is a digital progressive lens. Made with start of the art technology its one of the more comfortable options for people. Second to that, if the person has adaptation issues with a progressive design then a traditional bifocal or trifocal would be best.
What are daily wear lenses?
Daily wear lenses are contacts that you wear only throughout the day. You must remove your ‘daily wear’ contacts before going to sleep. Daily wear lenses are not necessarily the same thing as daily disposable contact lenses; there are certain daily wear lenses that can be worn for more than a single day’s wear before disposal. ‘Daily wear’ lenses can be replaced daily, weekly, or monthly depending on the brand of the contact lens. Essentially ‘daily wear’ refers to the wearing schedule of the lens.
Are there contact lenses for dry eye sufferers?
First it’s important to treat the patient’s dry eyes, but yes there are contact lenses for dry eye sufferers. Daily disposable contact lenses, specifically with a silicone hydrogel material, are the best type of soft contact lenses for patients suffering with dry eyes. These lenses, depending on the brand, allow for more oxygen permeability and are more hygienic on the eyes. With daily disposable contact lenses these are single-use contacts that are discarded after one day’s use, so they are less prone to lens deposits accumulating. Also, daily disposable contacts are sometimes found to feel more comfortable due to the thinner nature of the lens. Depending on the severity of dry eyes, there are also specialty hard contact lenses to help patients with severe dry eyes; such as scleral lenses.
What color frames suite darker skin?
The great thing about style and fashion is it's a matter of preference. There are no wrong answers. With darker skin tones you can pick a shade that is similar to the skin which will offer a slight contrast and that could be appealing. You could go darker for a bolder look. You could also go to the other end of the spectrum with something very bright and light to have a high level of contrast. It's really about the persons personality as much as aesthetics and what they enjoy and feel like they can pull off.
How are glasses lenses made?
It's a lengthy process from start to finish but we'll go over the broad strokes of it. Now there's two different ways of producing lens blanks, the disc that makes a lens. The first method was a blank was ground down into the proper dimensions that would constitute a
specific Rx. The newer method is that blanks are "cast" into a mold that is already the proper measurements for a given Rx so no grinding is needed. After the blank is finished it's sent out to an optician. The optician then uses a combination of machinery to size the blank into the frames they belong to. After all of this, you'll have a finished pair of glasses.
What contacts are the most comfortable?
Typically soft daily disposable contacts with a high oxygen permeability are the most comfortable for patients. The specific contact lens depends on the curvature of the patient’s eyes. Different contact lens brands have different parameters and optics, so a proper contact lens evaluation by your eye doctor has to be performed to see which lens fits the best on the patient’s eye to provide the most comfortable vision.
What are the benefits of hard contact lenses?
Hard contact lenses are custom designed to fit specifically on your eye, the fitting process is more precise than with soft lenses, so this results in a more personalized fit with the hard lenses. There are various benefits of hard contact lenses. One benefit is that hard lenses provide sharper vision. Since hard lenses are custom fitted to your eye and maintain their form better than soft lenses, this results in sharper clarity of vision. Another benefit is that hard contact lenses are better for patients who have a high level of astigmatism, irregular corneas, or keratoconus, because hard lenses retain their shape allowing for better vision whereas soft lenses would just take up the shape of the irregular cornea and not correct the vision as well. Other benefits of hard lenses is that this may be a better option for patients suffering with dry eyes because hard lenses are deposit resistant and do not dehydrate. Another benefit is that hard lenses are extremely durable.
What are trivex lenses?
Trivex lenses a certain material that lenses are made of. Lens material is usually broken into a few categories such as: CR-39, Polycarbonate, Trivex, and Hi-Index. Each one has it's perks and cons. Trivex is a highly rated impact resistant, lightweight and UV protected lens. It also has a higher abbe value compared to polycarbonate meaning the light moves through the lens a little cleaner making the vision more crisp and clear.
I have astigmatism and wear bifocals. Is there any chance I could ever wear contacts?
Yes. Over the years there have been many advancements in contact lens technology, so if you’re a patient who has astigmatism and also wears bifocals there are contact lens options available for you. These specific lenses are called “toric multifocal” contact lenses. As of right now these lenses only come in a monthly modality. Be sure to visit your eye doctor to get a proper contact lens evaluation and determine which lens provides the best vision and fit.
At what age can I start wearing contact lenses?
At what age can I start wearing contact lenses? Answer: Instead of using age to determine if a patient can start wearing contact lenses, it is best determined by their maturity level. Children as young as 8 years old can safely wear contact lenses. (In fact studies have shown that kids practice better contact lens hygiene than some teenagers!). There are several different factors that are taken into consideration when determining who is a good contact lens wearer candidate so be sure to visit your eye doctor today for a proper contact lens evaluation.
Do you carry contacts that can change my eye color?
Yes. Color contacts can be used for various reasons such as for theatrical/costume purposes, to provide a more subtle and natural look to enhance your eyes, or for medical purposes. Color contact lenses are a FDA medical device where an eye care provider must prescribe the lenses for you. Even if you have perfect 20/20 vision doesn’t mean you can get your color contacts from anywhere like randomly from online or from a beauty supply store (it’s actually illegal to do so!). It’s important to get a proper contact lens evaluation by an eye doctor because every eye surface is unique and each contact lens comes in different parameters, so we have to assess which lens is the best fit on your eye and the healthiest option. Color contacts can cause serious blinding infections if it’s not the proper fit, so be sure to get a proper contact lens evaluation from your eye doctor before purchasing color contact lenses.
Do i need an eye exam to wear contact lenses?
Definitely. Contact lenses are a medical device placed on your eye so you need a proper contact lens evaluation by your eye doctor. During the contact lens evaluation your eye doctor will determine which modality and what specific brand of contact lens is best for you. Different contacts come in different contact lens parameters, such as the power, curvature and diameter of the lens. Thus, it’s imperative for your eye doctor to conduct a proper contact lens evaluation to ensure proper vision and fit of the lens. This is especially important to reduce any risk of contact lens associated infections or eye problems/discomfort.
I was told I was not a good candidate for contact lenses, are there new options available today?
Over the years there have been a lot of advancements in the technology of how contact lenses are made. Contacts are now made of material that provide higher oxygen permeability. There has also been an increase in the contact lens parameters including higher minus and plus powers as well as contacts with astigmatism, and multifocals for patients with presbyopia. Thus, there may now be a new option available for you, depending on the reasons why you weren't previously a candidate for contact lenses. Be sure to visit your eye doctor to have a proper contact lens evaluation and discuss which lens options are best for you.
What contact lenses are best for younger kids?
Typically when determining whether kids are a good contact lens candidate, it doesn't really have to do so much with age, but more so with their maturity levels. In fact studies have shown that younger kids are actually less prone to contact lens associated problems than teenagers. There can be various types of contact lenses that are great for younger kids. If a child is part of the myopia management program, they typically do well in the hard ortho-keratology lenses or soft daily disposable multifocal lenses. What’s great about the daily disposable contacts is that it allows the child to wear a brand new pair of contacts every morning, so this minimizes the risk of infections and other problems that may be associated with wearing contact lenses. Soft contact lenses are also more comfortable on the eyes. However, each eye is different so it’s important to have a proper contact lens evaluation to see which contact lens is best for the child’s eye.Typically when determining whether kids are a good contact lens candidate, it doesn't really have to do so much with age, but more so with their maturity levels.

What lens material are best for kids?
The short answer is any lens material that's rated for impact resistance. Given the nature of children we don't want anything that can possibly chip or fracture and cause damage to a child's eyes. This eliminates CR-39 and Hi-index given their brittle nature. Polycarbonate and Trivex are the most impact resistant and therefore the safest for children.
What type of contact lenses are best for children?
When determining whether kids are a good contact lens candidate, typically it doesn't really have to do so much with age, but more so with their maturity levels. In fact studies have shown that younger kids are actually less prone to contact lens associated problems than teenagers. There can be various types of contact lenses that are great for younger kids. If a child is part of the myopia management program, they typically do well in the hard ortho-keratology lenses or soft daily disposable multifocal lenses. Children who are active and play sports would benefit from ortho-K lenses. Ortho-K lenses are hard lenses that are worn at night when the child is asleep and it gently reshapes the front part of the eye. When the child removes the lenses in the morning, they're able to see clearly without needing any glasses/contact lens correction throughout the day. In regards to soft daily disposable lenses, what’s great about them is that it allows the child to wear a brand new pair of contacts every morning, so this minimizes the risk of infections and other problems that may be associated with wearing contact lenses. Soft contact lenses are also more comfortable on the eyes. However each eye is different so it’s important to have a proper contact lens evaluation to see which contact lens is best for the child’s eye.
Why are one-day disposable contact lenses becoming so popular?
Daily disposable contact lenses are single-use contacts that are discarded after one day’s use. With this design you open up a fresh new pack every day. They are becoming more popular because they are considered one of the healthiest contact lens options for your eyes. Since dailies are less prone to lens deposits accumulating and less of a chance to develop contact lens related eye infections. There are also other advantages to dailies such as them being more convenient because there is no lens cleaning required and they do not need to be stored in a solution or case. Daily disposable contacts are also sometimes found to feel more comfortable due to the thinner nature of the lens.
Are disposable contact lenses good for my eyes?
Yes. Daily disposable contact lenses are single-use contacts that are discarded after one day’s use. With this design you open up a fresh new pack every day.

Daily disposable contacts are also sometimes found to feel more comfortable due to the thinner nature of the lens.
Are daily contact lenses better for eye allergy sufferers than monthlies?
Are daily contact lenses (dailies) better for eye allergy sufferers than monthlies? Answer: First it’s important to treat your eye allergies, but yes daily contact lenses are better than monthly contact lenses for patients who suffer with eye allergies. Dailies are single use contact lenses so you place a fresh new set of lenses into your eyes everyday. However with monthlies the same lens is used for 30 days so there is more protein and lipid deposits accumulating on the lens, and then when you place this lens on your eye it can cause irritation and discomfort. Dailies usually are also made of a thinner material so they feel more comfortable on your eyes than monthlies. Be sure to have a contact lens evaluation with your eye doctor to determine which lens is best for you.
What are the best lens options for UV protection?
So essentially all lenses when they're poured or cast have UV protection built into them. You can add to this protection with transition or photochromic lenses which block all UVA and UVB rays. Anti-glare coatings also offer protection as well as choosing to polarize your lenses instead of tinting them or getting transitions.
What are the advantages of daily disposable contact lenses?
Daily disposable contact lenses are single-use contacts that are discarded after one day’s use. With this design you open up a fresh new pack every day. There are several advantages of daily disposable contact lenses. For example,daily disposable contacts are more convenient because there is no lens cleaning required and they do not need to be stored in a solution or case. Daily disposable contact lenses are also healthier on the eyes since they are less prone to lens deposits accumulating and less of a chance to develop contact lens related eye infections. Daily disposable contacts are also sometimes found to feel more comfortable due to the thinner nature of the lens.
What is trifocal lenses?
It's essentially right in the name. The prefix "Tri" lets us know that there's three elements to the lens and when it's added to the suffix "focal" we can gather there's three focal points to the lens. Similar to the Bifocal, which is for reading and distance viewing, the trifocal adds one more viewing distance to the lens and thats the intermediate distance. Others may refer to this as the computer or office range. So in total the trifocal will let us read, use the intermediate range, and see at distance as well.
I keep hearing more and more about contact lenses that are thrown away every day. What is the advantage because it seems more expensive to me?
These are daily disposable contact lenses. Daily disposable contact lenses are single-use contacts that are discarded after one day’s use. With this design you open up a fresh new pack every day. There are several advantages of daily disposable contact lenses. For example, daily disposable contacts are more convenient because there is no lens cleaning required and they do not need to be stored in a solution or case. So although daily disposables may appear to be more expensive, you are actually saving money on not needing any contact lens solutions/cleaning agents or cases. Also, daily disposable contact lenses are healthier on the eyes since they are less prone to lens deposits accumulating and less of a chance to develop contact lens related eye infections. Daily disposable contacts are also sometimes found to feel more comfortable due to the thinner nature of the lens. Additionally, depending on the brand of contact lenses, they vary in prices and can be less expensive than some biweekly or monthly lenses. So, be sure to have a proper contact lens evaluation with your eye doctor so they can discuss which option is best for you.
What is better trivex or polycarbonate?
Ultimately I would have to say that Trivex is the better material for a handful of reasons. It has a higher abbe value which produces a sharper image so the overall optics of the lens are better than polycarbonate. Aside from that, Trivex is also a little bit lighter than poly. Trivex has a comparable level of impact resistance to poly as well as being 100% UV rated.
What is the highest index for glasses?
The highest index you can get for lenses is the 1.74
How can I reduce the thickness and weight of my eyeglass lenses?
The solution is typically two fold. If we have a higher prescription it can end up being a heavier lens. Second to that, depending on the style and material of the frame we have can also increase the overall weight. If we get our prescription made in a thinner lens material, such as Hi-index, and use a titanium frame then that is the best way of reducing overall weight. Less and lighter material is the solution to reducing the weight of our glasses and improving overall comfortability.
What are progressive lenses?
Progressive lenses are a touch tricky to explain but let's just review the basics. We can think if a progressive lens as a trifocal, a lens with three different prescriptions, without a line. It's composed of a distance zone, intermediate or computer/office zone, and a reading zone. In-between these three zones are a steady gradation of increasing or decreasing powers, relative to direction, which aid in viewing from distance to near. As the eye "progresses" up and down the lens these little quarter steps between focal points keeps everything clear and in order for us.
What is photochromic lenses?
Photochromic lenses are lenses that tint with exposure to UV light. Popularly known as transition lenses, they offer protection from the sun and its harmful UV rays. They accomplish this by adding a special dye to the lens which is light sensitive and darkens upon exposure to UV light.
What are aspheric lenses?
Aspheric lenses are generally used in high prescription cases. It can be used in both high plus and high minus lenses but the thinning effect is most noticeable for people with a high plus prescription. In aspheric lenses the curvature of the lens is changed which makes the lens thinner and also reduces or eliminates lens distortion or aberration. What this means is that the Rx is more likely to be clear across the breadth of the lens. In summation, a thinner and clearer lens is what an aspheric lens is.
What are transition lenses?
Transition lenses are lenses that tint upon being exposed to UV light. What this means is that when sunlight hits the lens it will darken and in the absence of sunlight it will revert to its clear form. The transition, or photochromic element, is available on all types of materials from plastic to polycarbonate.
Are there surgery free lasik alternatives?
The answer is yes and no. If your goal is to stay out of glasses and contacts throughout the day then there is an alternative called ortho-keratalogy (ortho-K) hard contact lenses. These are specialty lenses that are custom designed for you to sleep with at night; the lenses gently applies pressure and reshape your cornea (the front curvature of your eye) to safely and gently improve your vision, such that when you wake up in the morning and remove the lenses you’re able to see clearly without any correction throughout the day. However, the difference between LASIK and ortho-K is that ortho-K is not permanent, you have to wear the ortho-K lenses every night or else your cornea will go back to its original shape. Talk to your eye doctor to see which treatment you’re a better candidate for.
What lens materials give the clearest vision?
It really depends on the abbe value which is the scale that rates how well the light passes through the material. The cleaner it passes through the better the optics of a lens. The higher the abbe value more light will get correctly to its destination on the retina. CR-39 has the highest value, followed by trivex, then hi-index, and then polycarbonate. In that order you will have most to less clear in terms of material.
Is there ever a need for contact lenses after LASIK surgery?
Depends. If you got LASIK to correct your distance vision, you may need to wear contact lenses again once you reach presbyopia. Presbyopia is a normal part of age processing that starts around age 40-50 resulting in near vision blur. Thus you would need reading glasses/contacts to help you see clearly up close. Additionally, the front part of your eye is flattened after LASIK, so your eye doctor will have to choose a contact lens with a flatter curvature to properly fit on your eye.
What are digital progressive lenses?
There are two types of progressive or PAL lenses. Conventional PALs use the same template or design for every lens and every patient. This can lend itself to distortion or other visual issues for some wearers. Digital progressive lenses are tailor made using software to construct a progressive thats unique to every wearer. They do this by utilizing measurements specific to each wearer. This reduces or eliminates distortion, non-adapts, improves comfortability and clarity. All in all, digital progressive lenses are a good route to take when looking to manage presbyopia.
What are progressive lenses and how do they differ from ordinary bifocals?
Progressive lenses are similar to bifocals in having more than one prescription in them. However, whereas bifocals have two distinct and clearly separated areas of vision, progressives have a little more to them. In a progressive lens there are no hard, or curved lines, that visibly separate zones of vision. The lens is constructed in a way to gradually shift between distance, intermediate and reading zones in a comfortable and almost invisible progression.
What is the best way to select a pair of glasses?
The best way to select a frame is in person and with an experienced optical sales person. As helpful as pictures are, nothing will give a clear perspective like actually trying on a frame. Aside from that, an experienced optical professional will know the other factors to consider to get you into the right frame such as: age, complexion, gender, style, etc.
How do I store my glasses so they don't get scratched?
The best way to store our glasses when they are not in use is in their case. Keeping it in the case while sleeping, or not in use, will increase the odds that we don't end up with unseemly scratches on the lenses. Another way to reduce scratches is daily and preventative care. What this means is using a proper cloth and cleaning solution daily and properly storing it will keep our lenses in mint condition.
How often should I have my glasses prescription checked?
Barring any circumstance or diagnosis that would warrant frequent check-ups the general rule of thumb is yearly. At your annual eye exam you should have your prescription checked alongside the medical portion of the exam.
What should I do if my contacts get stuck in my eye?
First try not to panic! Some people may fear the contact lens may be trapped and go behind the eye into their brain, but don’t worry that’s impossible! If your contact lens is in the center of the eye and it’s just not coming off, then most likely the cause of your contacts getting stuck (if it’s a soft lens) is because the lens probably dried out. To help resolve this you can rinse your eye with a steady stream of sterile saline solution or use artificial tears, then close your eyes and gently massage your eyelids until you feel the lens move, then blink a couple of times and once the lens moves more freely then try again to remove your lens like you normally would. In the event your contact lens is dislodged from the center of your eye, then try to look in the opposite direction of where your lens would be. Again you can rinse your eye with sterile saline solution and gently massage your eyelids and blink to allow the lens to re-center and then remove like you normally would. In the event that you can’t get your contacts out, be sure to go to your eye doctor so they can help you remove it.
Can I use no-line bifocals with smaller frames?
Yes, you can use progressive lenses with smaller frames. Generally speaking, as long as there's about 25-30mm of vertical lens space then a progressive design should work.
What are bifocal glasses?
Bifocal glasses are a lens style that has two prescriptions in it. The prescriptions are typically one for distance and one for reading. Lenses with these two distinct zones are generally called bifocals.
What are tinted lenses?
Tinted lenses are lenses, prescription or not, that have had a dye added to them. The dye typically darkens the lenses and adds color. Tinted lenses are usually found in sunglasses to help protect from the UV rays.

How can I stop glare at night or at a computer?
Using a good antiglare coating will help reduce glare. Some are formulated better than others which will determine how much glare is reduced. There are varying models and levels of antiglare from a variety of companies. Do a little research and find out which one will work for you.

Can I wear contacts while I sleep?
Depends on the type of contact lens you’re wearing. If you’re wearing a hard Ortho-K specialty lens, then this lens is actually designed to be worn when you sleep. Additionally, if you specifically have an extended wear lens, then these lenses can also be worn while you sleep. However, in most cases contacts CANNOT be worn while you sleep, this is because it can cause various contact lens associated conditions. For instance, it can cause your eyes to dry out, as well as cause new blood vessels to start growing on your eyes because your eyes are deprived of oxygen, resulting in irritation, discomfort and blurry vision. Be sure to talk to your eye doctor about proper contact lens hygiene.
What happens if I wear my contacts longer than recommended?
If you wear contacts longer than recommended then this places you at a greater risk for developing contact lens associated eye infections and complications which can lead to permanent vision loss. It can result in scratches on your cornea, corneal ulcers, new blood vessels to grow on your eye, and make your eyes feel irritated, uncomfortable and painful. Different types of contacts lenses have different disposal schedules, for instance if you have dailies you must throw them away after a single use whereas if you have monthly lenses you must not wear them longer than 30 days. Contact lenses are a medical device so it’s very important to maintain proper contact lens hygiene, don’t overwear your lenses, and listen to your eye doctor’s wear schedule guidelines.
What are the best type of contact lenses ?
This is determined on a case by case basis. There is no one lens that fits the best on every patient. The curvature of patients’ eyes vary, so some lenses that may fit perfectly on one person can be too tight or too loose on another patient. Also, if someone has a very high astigmatism or an eye condition called keratoconus the best type of contact lens for them would be a hard lens, such as a rigid gas permeable lens or scleral lens, whereas for another patient a daily disposable soft contact lens may be best. Thus, be sure to get a proper contact lens evaluation by your eye doctor to determine what is the best type of contact lens for you specifically.

What can I do to alleviate discomfort after a full day of wearing contact lenses?
You can apply artificial tears to help alleviate discomfort. Also, if you feel like your lenses aren’t comfortable at the end of the day you can try to reduce the number of hours you wear your lenses, or talk to your eye doctor to possibly switch you into a different contact lens brand that allows for more oxygen permeability. Also, if you feel like your eyes are dry talk to your eye doctor to see what is the best dry eye treatment for you.
Why do my eyes feel irritated when I wear contacts?
You may have dry eyes which may cause your eyes to feel irritated when you wear your contacts. It’s important to treat the underlying cause of dry eyes to help relieve your symptoms. You may also be abusing your contact lenses, meaning you wear them longer than the contact lens wear schedule or you sleep in your lenses, and this improper contact lens hygiene may be the cause. Additionally, you may be wearing contacts that don’t have a high oxygen permeability so your eye doctor may need to switch you out into a different brand and/or a different contact lens modality. It’s important to have a proper contact lens evaluation by your eye doctor to determine the cause of your irritated eyes and then determine the best course of treatment for you.
Can I swim with contacts in?
NO! This can cause a lot of contact lens associated infections and problems such as eye infections, irritation and can even lead to permanent vision loss. It’s important to not expose the contacts to any type of water, including swimming pools, lakes, oceans, or tap water from showering. There can be various bugs, bacteria, microbes and viruses found in the water and if they are exposed to your contact lens they can latch onto the contact and cause an eye infection, inflammation, irritation, potential vision loss, and possibly require for you to get a corneal transplant. It’s important to remove your contacts before entering any bodies of water. Wear prescription swimming goggles instead.
I wear contact lenses, but now I’m having trouble seeing clearly to read things up close. What can I do?
This may mean that you’re approaching presbyopia where now you also need a reading prescription to see material clearly up close. There are several different options to help correct this. You may switch in a multifocal contact lens, which is a contact lens that has two different powers within one lens to allow you to see both at distance and near. You may also try out a monovision modality where one eye is corrected for distance and the other eye is corrected for near. You may also keep your regular contacts for distance and just wear reading glasses over your contact when you need to read things up close. Talk to your eye doctor to see which modality is best for you.
