It is as important to protect your eyes from ultraviolet (UV) rays as it is to protect your skin from damaging UV light. Accumulated exposure to UV rays has been implicated in the development of cataracts, retinal damage, and other serious eye problems. So, it is advisable that clear prescription eyeglass lenses have UV-blocking ability, especially if prescription eyeglasses are worn outdoors. Fortunately, getting this protection is as simple as ordering a UV-blocking coating. While high-index, polycarbonate, and Trivex lenses are inherently able to block UV light, the CR-39 plastic lenses commonly used for most prescription lenses have limited ability to do so. Thus, ordering the transparent UV-blocking coating for this type of lens is recommended.
Cumulative exposure to harmful ultraviolet (UV) rays has been linked to vision problems such as cataracts and retinal damage. Whether you enjoy walking, participate in sports, or drive to and from work, it’s important to protect your eyes from UV rays. At DR. DONALD B. KNAPP, OPTOMETRIST, we offer UV-ray protective coating on prescription lenses. We also carry prescription and non-prescription sunwear, athletic eyewear, and computer eyewear.
P.S. Photochromic lenses, which darken with exposure to ultraviolet radiation, also block 100 percent of UV rays without the need for a UV-blocking coating.
