How Do Sunglasses Protect Your Eyes? 

You probably already know sunglasses make you look cool. But there’s another reason you should wear them when spending time outdoors in strong sunlight. Sunglasses actually shield and protect your eyes from the harsh ultraviolet (UV) rays of the sun. By wearing sunglasses, you’re helping to protect your vision and your overall eye health. Your optician in Portland, OR, can tell you more about the many health benefits of wearing sunglasses.

Sunglasses Protect your Eyes From Long-Term UV Exposure

If you’re someone who spends a lot of time outdoors, you’re exposing your skin and eyes to the sun’s rays. These rays are composed of ultraviolet light that can pose health risks over time. As far as your vision, UV rays can contribute to cataracts and to macular degeneration — two conditions that impact the way you see the world. Cataracts are cloudy films that develop on the lenses of your eyes. Macular Degeneration involves the breakdown of your macula, which is part of your retina. Wearing sunglasses with protective coatings may help prevent both conditions. For the best protection, choose sunglasses that boast “UV absorption up to 400 nm.”

Polarized Sunglasses Protect Your Eyes From Glare

Polarized coatings on your sunglasses can help reduce instances of glare. Glare is defined as “uncomfortably brilliant light.” Glare can emanate from headlights, streetlights, or even reflect back from snow or sand. Polarized sunglasses help eliminate glare, making it easier to perform routine activities, such as driving or walking on the beach on bright, sunny days.

Mirrored Sunglasses Shield Your Eyes From Reflected Light

You’ll often see skiers and snowboarders wearing mirrored sunglasses, and for good reason. Mirrored glasses reduce the amount of reflected light that enters your eyes. This not only makes it easier to see where you’re going on ice and snow, but it can prevent you from freezing your cornea while riding a snowmobile, climbing a mountain, or wooshing down the slopes. You may have heard this referred to as snow blindness. Mirrored sunglasses help prevent this painful condition.
