Exposure to the ultraviolet component of sunlight causes damage to ocular tissues that can accumulate over a lifetime. " is chronic ultraviolet radiation UV R) exposure has been associated w ith pterygium, cataract, climatic droplet keratopathy, and other serious ocular conditions. As a result, m any spectacle lenses now other effective blocking of UV R transmission.However, recent work by K arlCitek, OD, PhD, and others has found that UV R can be reflected from the back side of clear, photochromic, and tinted/polarized lenses; and thatNo-G lare (antire$ective, or AR) technology actually increases the level of backside UV R reflection. Maximum protection from UV R requires that all lenses— including clear lenses intended primarily for indoor wear— effectively shield wearers from both transmitted and reflected UV R" is is now possible with Essilor’s new Crizal ® UV lenses with patented Broad Spectrum Technology; these lenses maximize long-term eye health by shielding eyes from exposure to transmitted and reflected UV R.
