All About Vision

Polycarbonate Lenses

Polycarbonate lenses are high index lenses that are known primarily for their exceptional impact resistance and anti-scratch coating. If you or your children are always bumping, scratching or dropping your eyeglasses, this is the material for you. Up to 10 times more impact resistant than standard plastic eyeglass lenses, polycarbonate is a first-rate option for people with an active lifestyle. Developed in the 1970s, polycarbonate has been protecting eyes for quite a while.

Superb Eye Safety

If you regularly engage in sports or physical activity, these tough, durable lenses provide an extra degree of safety for your eyes. In fact, most protective eye gear and sports goggles are made from polycarbonate lenses, even when no vision prescription is needed. In addition, polycarbonate boasts built-in protection from the sun’s UV rays, making this an ideal lens material for time spent outdoors.

Lightweight

The refractive index of polycarbonate lenses is 1.59, which results in a lens that’s 20% to 25% thinner than common plastic lenses. Weighing in at 30% lighter than regular lenses, polycarbonate takes a load off the bridge of your nose!

Trivex Lenses

Developed in 2001, Trivex lenses are constructed from a newer plastic that shares many properties with polycarbonate. While also thin, scratch-resistant, highly impact-resistant and lightweight, Trivex lenses may be slightly thicker than polycarbonate lenses. For some vision prescriptions, they may provide a better visual clarity and more scratch resistance than polycarbonate lenses.

Eyeglass Frames

Are you in the market or mood for a new pair of eyeglasses? The selection is vast, with many fashionable, attractive pairs of glasses to browse through. How can you narrow down your options and choose the style of frames that are best for you?

Questions to Ask Yourself When Choosing Eyewear

  1. What’s my taste? Do I prefer a bold or subtle expression? Do I favor modern lines, a retro look or more conservative, classic styles?
  2. Where do I plan to wear these frames- at work, in the backyard, or for social outings?
  3. What colors work best with my skin and hair tones?
  4. What are the primary colors in my wardrobe?
  5. What’s the shape of my face?
  6. Do I like my current eyeglasses? If not, then what’s the problem?

Bring this information to your optician when you pay a visit to the eyeglass store, and most of the work will already be done! Your optician, who is highly skilled and an expert in fitting your eyewear will be able to hone in quickly on the eyeglasses that are most suitable.

How to Judge Fit and Comfort

Research conducted by the eyewear industry indicates that women pay more attention to how eyeglasses appear on their face, while men are more interested in how they feel and fit. Yet even if looks are your primary concern, if your eyeglasses aren’t comfortable – you won’t be pleased for long.

To judge the fit of frames when trying them on:

  • Frames should be wide enough for your face and not too snug on sides of your head. The edges of your eyeglasses should extend beyond the sides of your face. This ensures that the temples won’t press in on your head as they rest on your ears.
  • The curves at the end of each temple should go past your ear without pushing down on it. If they don’t, then the temples aren’t long enough.
  • The built-in nose piece or silicone nose pads should fit comfortably and firmly, without pinching the bridge of your nose. Silicone nose pads can generally be adjusted.
  • Your glasses should be able to stay in place when you move your head to and fro. Nod a few times, turn your head right and left, and bend over to touch the floor. Make sure that your glasses don’t slip off.

Is One Pair of Eyeglasses Enough?

Take a look at your closet. You likely own more than one pair of shoes, right? Unless you’re on a very tight budget, more than one pair of eyeglasses isn’t a luxury. Eyewear is a hip accessory, and the same pair may not be appropriate for all parts of your modern lifestyle. Just like your clothing, your eyeglass needs differ for home, work and social occasions.

If owning a solitary pair is enough for you, then choose frames that you love and feel good about no matter what you’re wearing or where you go. These eyeglasses will be on your face constantly, so take your time and pick a style that fits your unique personality and vision requirements.

Lens Options for Eyeglasses

If you thought the trickiest part of choosing a new pair of glasses was the frame selection, think again. You should be putting just as much thought and consideration into the lenses that you select for your new specs.

Here’s why: The quality and type of lenses in your eyeglasses will not only correct your visual acuity, but they will allow you to continue to see your best through various conditions. Whether it is keeping the lenses free from scratches, fog, glare or UV rays, or making them stronger or more attractive, your eyeglass lenses can help to keep your eyes safe and comfortable wherever the day (or night) takes you.

Lens Coatings

Here are a variety of coatings that you can apply to your lenses to maintain optimal vision and comfort and to protect your lenses and your eyes.

Anti-reflective/Anti-glare Coatings

Anti-reflective (AR) also known as anti-glare coatings help reduce the reflections and glare on your lenses, improving your vision and comfort in high-glare environments, and the look of your glasses as well (you can see your eyes clearly without a reflection on the front of the lens). Reflections from the sun, television and computer screens and bright lights (especially when driving at night) can cause eye strain, headaches and difficulty seeing. AR coatings and lenses can reduce this effect, improving your vision quality and comfort in these circumstances.

Scratch Resistant Coatings

Scratches not only affect the smooth look of the surface of your glasses but they can disrupt your vision. A scratch-resistant coating adds an extra layer of protection on the surface of the lens to significantly reduce scratching. This coating is particularly great for kids who may tend to be a little more rough with their eyewear.

Ultraviolet Coatings

Ultraviolet (UV) coatings protect your eyes from harmful UV rays from the sun. This coating can turn standard lenses into UV blocking lenses that can block 100% of the UV light from entering your eyes. UV is linked to the development of a number of eye diseases such as cataracts, macular degeneration and retinal damage.

Anti-fog Coatings

Particularly if you live in a cold climate, you may have experienced walking indoors from the cold and having your glasses lenses fog up completely. This can take a few minutes to resolve and can be dangerous if you are driving or need to see clearly. Anti-fog coatings will eliminate this effect, creating a smooth transition from cold to hot environments.

Lens Options

You may want to go with an upgraded lens to improve the look, strength or functionality of your glasses.

High Index Lenses

High index lenses have a higher refractive index which means they reflect more light than standard prescription lenses. What this means for you, the consumer, is that they can be made thinner and lighter than traditional lenses. High index lenses are particularly popular with those that need a high prescription as they are able to avoid thick lenses, adding comfort and a smoother look, but a higher price tag.

Trivex or Polycarbonate Lenses

Trivex or polycarbonate lenses are impact resistant lenses – a fantastic choice for sports and safety eyewear as well as standard sunglasses and eyeglasses for active types or kids. These lenses also offer full UV protection and are lightweight for optimal comfort.

Polychromatic Lenses

Polychromatic lenses are made with special technology that turns them into sunglasses when exposed to sunlight. The lenses darken automatically when you go outside and return to normal when you go back indoors. Polychromatic lenses can come in a number of tint colors and are great when you need prescription sunglasses but don’t want to carry around or pay for another pair.

Aspheric Lenses

Aspheric lenses use advanced technology to create a slimmer, flatter and lighter lens than standard prescription lenses. While aspheric lenses can improve the appearance of any prescription lens, they are especially beneficial for those who are farsighted since those lenses tend to bulge out in the middle.

So the next time you are in the market for new eyeglasses, speak to your optometrist or optician about the best lens choices for your eyes, your vision and your lifestyle.

Contact Lens Basics

If you need vision correction for nearsightedness, farsightedness or astigmatism, contact lenses are a popular and effective option. In the United States, approximately 20% of the population who requires vision correction wears contact lenses. Currently dating back more than 125 years, contacts are presently available in a wide variety of materials and types. As opposed to the situation years ago, nowadays almost everyone can wear contact lenses.

Eyeglasses may be an attractive way to accessorize your outfit and make a fashion statement, yet you may sometimes prefer your appearance without glasses. Contact lenses allow you to have sharp vision without eyeglasses or costly vision surgery. Another benefit of contacts is that they grant a wider field of vision than glasses. This is a major advantage when it comes to playing sports or engaging in hobbies and professions such as photography.

If you are considering wearing contact lenses, you’ll need to schedule an initial eye exam and contact lens evaluation with your eye doctor. In the United States, contacts are regarded as medical devices that require a prescription by an eye care professional (ECP). In order to determine the best lenses for you, your ECP will assess your visual condition, structure of your eye and natural tear production.

Contact lenses are categorized depending upon the following factors:

  1. Material composition
  2. How long they can be worn before you have to take them out
  3. Life span- how long they can be used before you have to toss them and grab a new pair
  4. Design of the lenses

Material Composition of Contact Lenses

There are four different types of contact lens materials:

Soft Lenses

Over 90% of contact lenses on the market today are classified as soft lenses. These ultra-comfortable, thin contacts are constructed from gel-like plastics that contain a high percentage of water. They cover the entire cornea of your eye (clear front surface) and it is typically easy to adapt to wearing them.

First introduced in 1971, soft lenses used to be made from hydrogel materials. At present, silicone hydrogel is the most widespread, popular version. They permit a higher quantity of oxygen to reach the eye, which is healthy and comfortable.

Hard, Gas Permeable Lenses

Also called GP or RGP (rigid gas permeable) lenses, these contacts are smaller and made from plastics that have no water. They often provide the advantage of more acute vision, yet it generally takes longer to adapt to wearing them.

Hybrid Lenses

The center zone of these lenses is made from rigid gas permeable lenses, and a soft lens material encircles the border. Hybrid lenses thereby provide the best of both worlds – sharp vision from the center and a soft, comfortable border.

Wearing Time for Contact Lenses

The two primary kinds of contact lenses are daily wear and extended wear. Daily wear lenses must be removed on a nightly basis, and extended wear lenses may be worn up to seven days; a few brands of extended wear lenses are approved by the FDA for monthly wear (also known as “continuous wear” lenses). Extended wear lenses are very convenient even if you always remove them before going to sleep, as they are safe and comfortable for napping. Don’t sleep in your lenses unless you’ve discussed this with your doctor, since improper wear times can lead to corneal damage.

Life Span for Contact Lenses

All contact lenses must be discarded after a specified amount of time, even if you care for them well and properly. Soft contact lenses in particular accumulate lens deposits and contamination, which raises your risk of eye infections.

  • Daily disposable lenses: the most convenient and healthiest option, these lenses are replaced after one day of wear
  • Overnight disposable lenses (kept in your eyes overnight): must be replaced after one week
  • Monthly wear lenses: these are discarded after wearing for 30 days.
  • Gas permeable contact lenses: these are more resistant to lens deposits and can last up to a year or in many cases even longer with excellent care.

Designs for Contact Lenses

Contact lenses vary depending upon the type of vision correction that is required. The most common design is spherical, which works for nearsightedness, farsightedness and astigmatism. Toric lenses, which come in both soft and GP versions, possess multiple lens powers to correct astigmatism. Bifocal and multifocal lenses utilize a number of zones for different viewing needs, such as near, intermediate and far vision. They are often a good option for presbyopia. Orthokeratology (ortho-k) lenses are designed to reshape the cornea overnight, which corrects daytime vision without a need for eyeglasses or lenses.

Additional Features of Contact Lenses

Colored contacts: Lenses can be worn in color tints that enhance the natural color of your eyes or change your eye color totally. Blue eyes can be made more vibrant, or brown eyes can be altered to green.

Special-effect contacts: These lenses offer an extreme change to the color of your eyes and are generally used for costumes or theatrical effects. You can look like a zombie, an animal, or whatever you envision!

Prosthetic contacts: Disfigurations caused by disease or accidents can be masked by these colored contact lenses. With a medical orientation, prosthetic lenses are generally used to match the appearance of both eyes.

Contact Lenses that are Right for You

To identify the lenses that are ideal for your needs, you must first have a complete eye examination and contact lens evaluation performed by your eye doctor. Your ocular health will be inspected and detailed measurements of your eyes will be taken. Trial lenses will be inserted to check for the best possible and most comfortable fit and vision

After your initial fitting, follow-up visits for contact lenses are important. Your eye doctor will check that the fit is right and that no complications are developing. Your tolerance to contact lenses will be assessed. Sometimes a change in the fit or type of lens is necessary.

Your contact lens prescription will be issued after the fitting process is complete.

Proper Care and Handling of Contact Lenses

It is relatively simple to care for contact lenses. A single, multi-purpose lens solution is generally all that’s required for cleaning, disinfecting and storing your lenses. With daily disposables, routine care is totally eliminated and you can enjoy the feeling of a brand new fresh clean lens every day.

Your eye doctor or contact lens technician will instruct you how to take care of your contact lenses before you leave the office.

Why are Eye Exams Important?

For both adults and children alike, eye exams are an important part of one’s general health maintenance and assessment. Your eyes should be checked regularly to ensure that you are able to see as best as possible. Regular eye health exams will also check for signs of eye disease or conditions that can affect not only your vision but your overall health. Vision and eye health is such a critical part in learning and development, therefore, we highly recommend eye exams for infants and children.

Vision Screening vs. an Eye Exam

When we recommend regular eye exams, this should not be confused with a vision screening. A vision screening is a basic test that indicates if you have difficulty seeing and require further assessment and corrective measures. It can be performed by anyone, whether it is a school nurse, a pediatrician or even a volunteer at a vision clinic. A vision screening usually only checks vision, it does not check eye health. Also, most vision screenings for kids only check for nearsightedness (when you can not see far), but what happens when the majority of children are farsighted? Most of the time many of these kids get overlooked.

A comprehensive eye exam on the other hand, can only be performed by an eye doctor as it requires special knowledge and equipment to look around and into your eye to check your eye and vision health. Such an exam can assess whether there are underlying causes for vision problems and whether there are any signs of disease which can threaten your site and the health of your eye. A comprehensive eye examination can also diagnose symptoms of diabetes, high blood pressure, high cholesterol, tumors, cancer, autoimmune disorders, and thyroid disorders. A comprehensive eye examination will also provide an accurate prescription for eyeglasses or contact lenses.

Eye Exams for Eye Health

Eye exams are critical because many vision threatening eye diseases such as glaucoma, macular degeneration, cataracts, or diabetic retinopathy have no or minimal symptoms until the disease has progressed. In these cases, early detection and treatment is essential to halting or slowing down the progression of the disease and saving eyesight. During a comprehensive eye examination, your eye doctor will be looking for initial signs of these diseases. If a problem with your eyes arises such as red eyes, eye allergies, dry eyes, eye swelling,eye pain, always seek an eye doctor as your first doctor to call since they are specifically trained to treat eye diseases.

Eye Exams and Children

If your child is having developmental delays or trouble in school there could be an underlying vision problem. Proper learning, motor development, reading, and many other skills are dependent upon not only good vision, but your eyes functioning together. Children that have problems with focusing or hand-eye coordination will often experience frustration and may exhibit behavioral problems as well. Often they don’t know that the vision they are experiencing is abnormal so they aren’t able to express that they need help. Many conditions are much easier to treat when they are caught early while the eyes are still developing, so it is important to diagnose any eye health and vision issues as early as possible.

Eye Exams Over 40

Just like the rest of our bodies, our eyes begin to weaken as we age. There are a number of common age-related eye conditions such as presbyopia, cataracts, and age-related macular degeneration that can begin to affect your vision and your daily life. While some of these conditions are more of an inconvenience, others could lead to vision loss and dependency.

In addition to regular yearly eye exams, it is important to be aware of any changes in your eye health and vision. Also know your potential risk factors as well as your family ocular and medical history. Over half of the vision loss worldwide is preventable with proper treatment and care.

Preparing for an Eye Exam

For both adults and children, an eye exam is a critical part in maintaining your overall health and well-being, and therefore, regular eye exams should be incorporated into your health routine. Comprehensive eye exams assess your vision and the health of your eye, looking for early signs of disease that may not have obvious symptoms. You should not wait until you experience a vision problem or symptoms of an eye condition to schedule a routine exam.

Depending on your age, family history, general health and eye health, it is recommended to have an eye exam every one to two years. Of course if you experience any serious symptoms that affect your eyes or your vision, you should contact your eye doctor immediately.

The Difference Between an Optometrist (OD) and an Ophthalmologist (MD or DO)

Confusion about the difference between optometrists and ophthalmologists is common, and many people are not aware of how the two eye care professionals differ.

Optometrists

Optometrists or Doctors of Optometry attend optometry school which is usually at least four years of graduate level training. They are able to perform eye exams, provide prescriptions for eyeglasses and contact lenses, and diagnose and treat eye diseases as as glaucoma, dry eyes, or eye infections that may require medication or drops. They can consult with and co-manage patients in pre- or post-op surgical care, however they do not perform surgery.

Ophthalmologists

Ophthalmologists are medical doctors that attend medical school and later specialize in ophthalmology. They are able to do all of the services mentioned above but also perform eye surgeries such as cataract surgery, refractive surgery such as LASIK and deal with more urgent eye conditions such as retinal detachment.

Infant and Child Eye Exams

According to the American Optometric Association (AOA) children should have their eyes examined by an eye doctor at 6 months, 3 years, at the start of school and then at least every 2 years following. If there are any signs that there may be a vision problem or if the child has certain risk factors (such as developmental delays, premature birth, crossed eyes, family history or previous injuries) more frequent exams are recommended. A child that wears eyeglasses or contact lenses should have his or her eyes examined yearly.

Adult Eye Exams

Healthy adults under 40 with good vision and who do not wear eyeglasses or contact lenses are recommended to have an eye exam at least every two years. Those that do use vision correction or have a health issue such as diabetes, high blood pressure or another health condition that can have an impact on your eye health should schedule a yearly exam, unless the eye doctor recommends more frequent visits.

Once you reach 40, you become susceptible to a number of age-related eye conditions such as presbyopia, cataracts or macular degeneration, therefore annual or bi-annual exams are strongly recommended.

As you continue to age, particularly after age 55, the risks of eye disease increase, and early detection can be critical to preventing significant vision loss or blindness. Scheduling a yearly eye exam can make all the difference in maintaining your independence and quality of life.

How to Prepare for Your Exam

Prior to your exam you should decide whether you will be seeking special services such as a contact lens exam or LASIK consultation. These services may cost extra. Check with the doctor’s office or your insurance provider to see if they cover any of the exam expenses.

You need to know if you have medical insurance, vision plan coverage or both. Medical insurance usually does not cover “wellness/refractive” exams for glasses or contact lenses. Vision plans will cover exams for glasses or contacts, but usually cannot be used for red eyes, floaters, or other medical eye health problems. Please bring your insurance cards with you.

In addition to bringing your current pair of glasses or contacts if applicable, it is important to be aware of your personal and family history and to have a list of medications or supplements you are currently taking. Your pupils will probably be dilated as apart of your exam, so plan accordingly.

Nonprescription Sunglasses

Everyone should have a good pair of sunglasses. Whether you wear prescription eyeglasses or not, sunglasses are important for every age, race and gender. While sunglasses may be considered a must-have fashion accessory, even more importantly, they play a critical role in protecting your eyes from UV (ultraviolet) and other harmful radiation from the sun. They also shield your eyes from wind, dust and debris that could cause discomfort, dryness or damage.

Sunglasses should be worn in the winter as well as the summer and should be 100% UV blocking. This doesn’t mean that you have to pay a fortune for your shades. Even cheaper brands of sunglasses are made these days with full UV protection, so take the extra time to ensure you select ones that do offer full protection from the sun’s rays.

Frame Materials

Sunglass frames are made in a wide variety of materials from plastics and acetates, to wood and natural materials to metals, such as aluminum, steel or titanium. Before you select a pair of frames, think about your lifestyle and what type of material will be most suitable for you. If you live an active lifestyle, sturdy and durable frames are a must. If you have sensitive skin, look for a pair made with hypoallergenic material that is light and fits comfortably. Make sure you select a pair that fits well, looks good and properly blocks the sun to ensure that you feel confident and comfortable when you are wearing them.

Sunglasses Shapes

Sunglasses serve as a combination of function and fashion and therefore come in a plethora of shapes and styles. Sunglasses are often larger than eyeglasses to cover more surface area and prevent sunlight from entering around the lenses. While fashion sunglasses are made in all of the latest styles from aviator to cat eyes, round, square and oversized, sports sunglasses are generally more durable and broad, often in wraparound styles that prevent sunlight from entering from the sides as well. Wrap-around frames are a good option for athletes, fishermen and bikers that spend a lot of time outdoors in the sun.

Lenses

Lenses are the most important part of any pair of sunglasses. As mentioned above, all lenses should block 100% UV rays but beyond that there are many options for sunglass lenses. Polycarbonate or trivex lenses are impact-resistant to increase safety during sports and outdoor activities. Polarized lenses help to reduce glare and are particularly helpful during activities on or near the water such as boating, fishing or beaching. Anti-glare and anti-scratch coatings are also beneficial to maintain your best vision in a variety of conditions.

For the fashion conscious there are a number of colors and reflective coatings available for sunglass lenses. It’s best to choose the lenses that allow for the most accurate color vision with the least amount of distortion to ensure they don’t obstruct clear vision.

While it’s important to choose sunglasses that you like from a style and appearance perspective, it’s also important to pay attention to comfort and fit. Here are a few tips for purchasing sunglasses that fit well for maximum comfort and sun protection:

  1. Make sure the lenses completely cover your eyes and provide extra coverage above and to the sides.
  2. The frames shouldn’t pinch at your temples or the nosepiece and should be wide enough for your face.
  3. Ensure that the frames aren’t too wide and stay in place when you move your head around.

Sunglasses for Prescription Eyeglass Users

If you wear prescription eyeglasses there are a number of options for sun protection. These options include prescription sunglasses, photochromic lenses (which turn from clear lenses to dark when you go outside), clip-ons, fitovers (which are sunglasses that go over your prescription eyewear) or wearing contact lenses with plano (non-prescription) sunglasses. Speak to your optician to determine the best option for you.

Prescription Sunglasses

Sunglasses are an important way to protect your eyes and ensure clear and comfortable vision when you are on the go. In addition to causing temporary vision loss, the sun’s bright rays can lead to long term eye damage. Ultraviolet radiation from the sun can also cause sunburns on the eyes and over time, can lead to diseases such as macular degeneration.

For those who wear prescription eyeglasses, sun protection is available in a number of options including prescription sunglasses, photochromic lenses or eyeglasses with clip-on sunglass lenses. The best solution depends on your personal preferences, comfort and which option fits in best with your lifestyle.

Prescription Sunglasses

These days, sunglasses are not only highly fashionable but remarkably functional for a wide variety of activities. Sport and athletic sunglasses for example provide eye protection, reduced glare and better contrast to improve performance in a range of outdoor conditions. Individuals with prescription eyewear can also benefit from the advantages of these specialty eyewear by purchasing prescription lenses.

Prescription sunglasses are available for virtually all vision prescriptions including those for farsightedness, nearsightedness and astigmatism, as well as bifocal and progressive lenses. Almost any pair of sunglasses can be fit with prescription lenses as long as the shape of the lens doesn’t distort vision (which happens for example with extremely wide wraparound lenses). Therefore if the latest pair of designer sunglasses catches your eye, there should be no problem in fitting a prescription lens to the frame.

You can also get prescription lenses in most lens materials and with most lens coatings, including polarized lenses (for glare protection), tinted lenses, anti-scratch coatings, polycarbonate or Trivex lenses (for extra durability) and more.

Even for those individuals who do wear contact lenses, prescription sunglasses are a fantastic solution when you prefer not to wear your contacts, such as when your eyes feel dry or irritated (during allergy season or in dusty or sandy locations for example), when you are going swimming (it’s advised not to wear contact lenses swimming in any body of water due to risk of infection) or when you just don’t want to deal with the hassle of contacts. Prescription sunglasses give you yet another option for comfort, safety and great vision.

Photochromic Lenses

Photochromic lenses are another alternative for the prescription eyeglass wearer. These lenses darken in response to sunlight turning your regular prescription eyewear into prescription sunglasses. Photochromic lenses are a convenient solution for glasses wearers who find it a hassle to carry around two pairs of glasses. No matter what shape or style, you can protect your eyes and spruce up your outdoor look or your sports performance with a pair of prescription sunglasses.

Sunglasses for Kids

Many parents don’t know the importance of sunglasses for children and don’t stress that they wear them, especially given the hassle involved in encouraging children to wear them and take care of them properly. However, studies show that since we spend so much time outdoors and in the sunshine as children that by the age of 18, our eyes and body have absorbed half of our lifetime ultraviolet radiation (UV) exposure. This makes the use of sunglasses and proper UV protection even more critical for children.

Risks to children’s eyes from overexposure to the sun can be short term and long term. Short terms risks include photokeratitis also known as “snow blindness” which is essentially a sunburn of the eye. Photokeratitis can cause temporary vision loss for up to 48 hours. Pterygium is another condition, also referred to as “surfer’s eye,” which causes an itchy, swollen growth to form on the surface of the eye. Pterygium often require surgery to remove.

Long term UV damage is known to be a risk factor for a number of eye diseases including cataracts (a clouding of the lens of the eye that causes vision loss) and age-related macular degeneration, which also causes permanent vision loss and low vision, as well as cancer of the eye, eyelid or the skin around the eye. Wearing sunglasses with wide or wrap-around lenses will protect not only your eyes, but also the area around your eyes from UV exposure and damage. Since these diseases can be caused by an accumulation of UV exposure over a lifetime, it is important to start preventative measures early, by getting children in the habit of wearing sunglasses when they are outside.

Quality sunglasses for children are easy to find these days, you just have to know what to look for. Firstly, you want to make sure that the lenses have 100% UVA and UVB protection and block UV absorption up to 400 nanometers. You also want to ensure that the frames completely cover as much of the eye and its surrounding as possible. Many frames will come with a band to help hold the sunglasses in place and prevent loss. You may also choose to buy polycarbonate or trivex lenses, as they are more durable and impact resistant which is particularly helpful for active kids.

Children that already wear eyeglasses can consider photochromic lenses (which darken in response to sunlight) which basically gives them two pairs of glasses for the price of one. With photochromic lenses, you don’t need to worry about your children switching, and misplacing glasses when they go in or outdoors.

As with any glasses purchase, ask your optician about the policy for lost or broken sunglasses. Make sure you get a strong storage case and discuss with your child the best ways to keep the sunglasses safe and secure.

Lastly, let your child be involved in the process of selecting sunglasses, as any child will be more enthusiastic about wearing shades that he or she picked out and loves.

Performance and Sport Sunglasses

Whether you are out on the field, the golf course, the waves or the mountains, you want your sunglasses to protect your eyes from the sun and enhance your visual experience. Sports and performance sunglasses are more than sun protection, they need to be designed for optimal, fit, comfort, acuity and strength, based on the demands of the sport or leisure activity you pursue.

Each element of your sports eyewear needs to be designed for active wear and to stand up to the tests of extreme weather conditions, rough play, impact and of course the sun. If you are fishing for example, you need anti-glare protection in your lenses for when the sun’s bright rays reflect off the water, you need a broad frame to keep out the mist and wind and you need strong frames and lenses for impact resistance. Most importantly, depending on your sport of choice, your glasses should assist in creating an enhanced visual experience so you can see and perform at your best.

Performance Sport Lenses

The first consideration when selecting your sports eyewear is the lens. You likely want a lightweight, strong and durable lens that can withstand impact from debris, other athletes, balls or falls. The leading lenses in this arena are polycarbonate or trivex lenses which are made from highly impact resistant plastic that has built-in UV protection.

Glare can be an annoying and uncomfortable distraction in outdoor activities, which can reduce vision and have a negative impact on sports performance. Polarized lenses will help to reduce the glare that is reflected off of wet, icy or shiny surfaces. Lens tints and coatings (such as anti-glare or anti-scratch coatings) can also help to improve visual clarity and can serve to reduce glare and to enhance contrast sensitivity to improve vision and therefore performance in certain outdoor activities. Some sports sunglasses come with interchangeable lenses of different tints to allow you to choose the contrast that most suits the conditions you are playing in.

Sport Frames

When selecting sports sunglass frames, the most important consideration is whether they have a comfortable and secure fit. Look for a pair that is strong and durable, yet lightweight and that doesn’t press into your face and cause discomfort at the temples or the bridge of the nose. For some sports like snowboarding, sports goggles might be the best option for the weather conditions and specific nature of the movement. Some frame options come with grips on the nose pads or temples to avoid slippage, particularly when you perspire.

Sports sunglasses are available in a variety of styles, shapes and sizes and the type that is best for you largely depends on the activities you participate in and what they demand. It is best to consult with your eye doctor or optician to get a full picture of your eye, vision and athletic needs in order to find the best pair of sports sunglasses for you.
