National Sunglasses Day is June 27. Sunglasses are important to wear year round, and by everyone in your family including kids, contact lens, glasses and non-glasses wearers. When it comes to sunglasses, there are a few key things that you should be considering: protection, functionality, and style.
Protection From UV
Protecting your eyes from Ultraviolet (UV) light is the most important aspect of sunglasses. Did you know you can actually get a sunburn on your eyes? It’s true, it’s called photokeratitis and can occur after being overexposed to UV in a short amount of time. Although typically temporary, it can be painful and cause your eyes to be light sensitive, red, and watery.
Long term exposure to UV, even in small amounts, can lead to more serious conditions. Chances of developing cataracts, macular degeneration and damage to the retina are all increased after exposure to UV. Skin cancer can also be a major concern for the eyelids and skin around the eye. In fact, 5-10% of all skin cancer is on the eyelid.
When purchasing sunglasses make sure that they are made to block UV. Sunglasses should be blocking 99-100% of UV-A and UV-B. A tinted lens with no UV protection can actually cause more harm than going without sunglasses.
UV is transmitted and reflected. While a sunglass with UV protection protects against transmitted UV, there is still concern for reflected UV. Reflected UV occurs when it is reflected off the back side of the lens, and into your eye. Adding an anti-reflective or no-glare coating to the back side of the lens will significantly reduce reflected UV from damaging your eye.
It is important to protect your eyes from injury too. For those who participate in high-impact sports, it is imperative that you choose a polycarbonate or trivex lens material. These lens materials are impact resistant and will protect your eyes from injury.
Polarized lenses are highly recommended by Dr. Knutson. Polarized lenses eliminate blinding glare, sharpen vision, and make colors appear more vibrant. Polarized lenses are excellent for driving, water sports, the beach or pool, and many other activities.
The color of lens you choose is also important. Most sunglasses are either grey or brown, however there are more options. Grey and green lenses allow things to appear the most natural in color. Grey lenses are best for baseball and softball players, fishing, running and cycling. Green lenses work well for golfers. Brown lenses are great for hikers and motorcycle riders. Amber and yellow lenses provide excellent contrast for trap shooters. Lenses are also available in blue, plum, grape and a few other colors.
Mirror coatings provide style and function. A mirror sunglass lens eliminates glare from sand, water, snow and other reflective surfaces. Mirrors also enhance the appearance of a lens by creating a shiny reflective look. Your eyes will not be visible through the lens by people looking at you, while your vision remains crisp and clear.
Last but not least, there are different frame styles to take into consideration. Fashion frames are very popular and work well for everyday activities. Sport or wrap sunglass frames are great for those participating in sports, cycling and driving. Wrapped sunglasses provide additional protection and ultimate field of vision.
