Protective UV Sunglasses: How to Choose a Good Pair
Sunglasses can be fun and sassy—it can make bold fashion statement or lend mystery to your persona. Sunglasses can also cut out glare or hide your puffy eyes for instance. They are cool, fashionable and desirable and most of us own a pair. But beyond cosmetic, practical and aesthetic reasons, do sunglasses serve a higher purpose? Yes!—but not just any pair of sunglasses but those with UV certified protection. This is a definite must if you want to protect your eyes and enjoy eye health. According to Micheal Kutryb, M.D. ophthalmologist and clinical correspondent for the Academy of Ophthamology, “UV radiation, whether from natural sunlight or indoor artificial rays, can damage the eye’s surface tissues as well as the cornea and lens.” That means a host of potentially blinding eye diseases like early cataract formation, macular degeneration, tumors, formation of Pinguecula (tiny yellow bumps on the white of the eye) and tumors.
Unfortunately, there are no way to immune your eyes to harmful UV rays from the sun. Since more than 99 percent of the UV radiation is absorbed by the anterior of the eyes, UV sunglasses are your best bet to protect the eyes. Exposure to sunlight can cause eye sunburn—(yes, your eyes can get sunburn too), a condition referred to as phytokeratitis, whereby your eyes hurt, become red or teary and are extremely sensitive to light. Although these symptoms are more annoying than dangerous initially, prolonged exposure to UV rays brings about consequences mentioned above. Certain bright surfaces like water, snow or white sand, even pavement can reflect UV light from the sun and damage the eyes’ front surface.
With so much at stake, choosing a pair of protective sunglasses is crucial. Just how do you go about choosing a right pair? Thankfully, the American Academy of Opthalmology offers these helpful tips for selecting the right pair of sunglasses:
· Check that the sunglasses offer 100 percent UV-A rays (shorter wavelength) and UV-B (longer wavelength) protection. Not all sunglasses with a UV tag are indeed UV-coated. It is safer to buy UV sunglasses from an optometrist’s office or a licensed optician. When in doubt, have the optometrist or ophthalmologist check it.
· The darkness of the sunglasses lenses does not determine level of UV protection. Eye experts suggest choosing green, grey or brown lenses as they filter out UV rays better.
· Price does not determine UV protection too. A pricier pair of sunglasses doesn’t necessarily offer more UV protection.
· Opt for wrap-around styles, where the sunglasses fit snugly around the areas around the eyes to filter out UV radiation from peripheral areas around the sides of the face and from above.
· Don’t rely on contact lenses to offer protection from the sun, even UV-coated ones since they only cover a small area of your eyes. Always wear a pair of sunglasses over your contact lenses.
Often, you are confronted with choices of lenses and they serve different purposes. Depending on your needs, these various types of lenses can further help you by reducing glare. Most come without UV protection but you can have them coated with UV protection:
- Blue-blocking lenses. They are typically yellow and orange and are thought to make distant objects clearer, especially in low lights. However, blue-blocking lenses may make it hard to discriminate the hues in the traffic lights.
- Polarized lenses. If you love water sports or spend lots of time in the sunlight, polarized lenses are a great option. They act like mini Venetian blinds that are set at specific angle to filter out a myriad of lights from various light-glinting sources. They reduce glare and prevent eye fatigue.
- Photochromic lenses or Transitional lenses. They help to reduce glare and maintain clarity, although they take time to adjust to different light conditions. Caution: Since lenses take time to adjust to light conditions, you may have difficulty seeing at first when you suddenly enter a dim area.
- Polycarbonate lenses. If you are heavily involved with contact sports or any kind of rough physical activities, polycarbonate lenses offer protection from impact injuries. They also provide adequate UV protection.
- Mirror-coated lenses. They offer protection in direct sunlight for extended periods of time. If you love outdoor activities or you work in construction or you’re a police officer, you can definitely use a pair of mirror-coated lenses.
According to Mayo clinic emeritus ophthalmologist, Dennis Robertson, M.D., any standard prescription eyeglasses can be treated with UV protection while retaining its clear appearance. That way, you get the protection you need without the dark shade.
It’s never too young to start wearing protective sunglasses. Wear them whenever you’re out, especially between the hours of 10 in the morning to 3 in the afternoon, when the sun is especially intense. Don’t be fooled by an overcast sky, thinking that it’s alright to step out without your sunglasses—UV rays have a way of penetrating haze and thin clouds. Put them on when you drive as they help to cut out glare and UV rays reflecting off shiny surfaces. Thankfully, protective sunglasses can also jazz up an outfit or highlight your facial features in a good way if you choose a flattering shape.
Talking about flattering shades, you also need some know-how as to what types of shades will enhance your face. Trace the outline of your face to determine your face shape. Do you have a round face or square or oval?—carefully chosen shades with some measure of fashion wisdom can greatly enhance your look.
- Square Face: To soften the “squareness” of your face, pick rounded glasses and lenses that are not as wide as the widest part of your face. It will diffuse the appearance of a broad jaw line. Eye experts suggest round frames.
- Oval Face. If you’re blessed with an oval face, your shade-picking job is much easier. Since your face is naturally symmetrical, all you have to worry is picking one that is proportionate to your face---not overwhelming or too small.
- Round Face. Since it is circular, you need to add angular dimensions to balance the “roundness” of your face. Angular shades will also add definition and highlight your features. Eye expert picks: Pick rectangular sunglasses frame.
- Rectangle Face. Since your face is elongated, diffuse length with round frames. In addition, look for glasses that add width to your face to cut down on the narrow dimension. Eye experts suggest any round frames or big sunglasses.
- Diamond Face. Your face is narrow across the temples and across your chin. Pick sunglasses that add width to the areas above the cheekbone. Eye experts suggest oval frames or rimless styles.
- Triangle Face. you need to broaden the area above your cheekbone to offset your wide chin area. This will help to restore symmetry and balance. Eye experts recommend broad sunglasses, wide at the sides.
Now, that you are equipped to shop for stunning sunglasses that can offer more than a dollop of sun protection, go and get yourself a pair of drop-dead gorgeous shades. When fashion meets function, you can step out in style.
