UV Exposure: Cataracts and Macular Degeneration
Who is at risk from UV rays? Everyone. Unfortunately, no one is immune to sunlight-related eye disorders. Ultraviolet (UV) radiation comprises of invisible high energy rays from the sun. UV radiation is known to be a contributing cause of cataracts and macular degeneration. The good news is there are steps you can take to help protect yourself.
Ask Your Doctor
Getting a complete annual eye exam is the most important step you can take to help monitor and protect your vision health. It is also important to use lenses that block 100% of the harmful UV rays you are exposed to on a daily basis.
To check whether your eyewear provides UV protection, you can go to an eyecare professional to have your lenses measured for UV absorption. The UV meter takes only a few seconds to read and will ensure that you are properly protected.
Know Your Lenses
Sun glasses don’t necessarily mean UV protection. It is a myth that tinted glasses or all sunglasses protect you from UV exposure. UV protection is not a function of the color of the lens but of the material used. Therefore some clear lenses can protect you from harmful UV exposure. Polycarbonate lenses are clear lenses that provide 100% UV protection with or without tint or color.
Photochromic lenses change to be as dark as necessary in proportion to the intensity of UV rays. They also provide protection, comfort and optimized vision.
Polarized lenses have a special filter that blocks glare. Glare occurs when natural light waves hit reflective surfaces such as pavement, windshields or snow. Glare can be very harsh to unprotected eyes and can alter perceptions of shapes, colors and contrast. Polarized lenses significantly reduce this glare and allow wearers to be in the sun without squinting. This reduces eyestrain and facial tension. High-quality polarized lenses also offer 100% UV protection.
