Ultraviolet and the Eyes

Ultraviolet (UV) Radiation and Your Eyes As youre putting on sunscreen this summer, remember that your eye are just as unguarded as your skin is to sun damage. To cheer your eye from abusive solar beam, sunglasses should block 100 per centum of UV rays and also absorb most HEV rays. Frames with a confining wraparound elbow room provide the best protection be take they limit how much turn over sunniness removees your eyes from above and beyond the periphery of your sunglass lenses. To protect your eyes outdoors, wear broad-brimmed hats and wraparound sunglasses with 100 percent UV protection.

Fortunately, the atmospheres ozone layer bloc ks virtually all UVC rays. UVB rays postulate slightly chronic wavelengths (280315 nm) and write down zilch than UVC rays. These rays are filtered partially by the ozone layer, but some hitherto finish off the earths surface. UVA rays are closer to visible light rays and have lower energy than UVB and UVC rays. But UVA rays can chap through the cornea and reach the lens and retina inside the eye.

Overexposure to UVA radiation has been linked to the development of original types of cataracts, and research suggests UVA rays may play a role in development of macular degeneration. Ultraviolet (UV) rays are higher (prenominal) in energy and do not fall deep! down the realm of visible light. In the electromagnetic spectrum, radio waves have the lowest energy, and da Gamma rays have the highest energy. As the consult suggests, high-energy visible (HEV) radiation, or blue light, is visible. Although HEV rays have longer wavelengths (400500 nm) and lower energy than UV rays, they penetrate deep into the eye and can cause retinal damage.
