These rays are filtered partially by the ozone layer, but some serene 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 back up through the cornea and reach the lens and retina inside the eye.

Overexposure to UVA radiation has been link 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 high in energy and do not fall within the realm of visi ble light. In the electromagnetic spectrum, ! radio waves have the lowest energy, and da Gamma rays have the highest energy. As the mention 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 profoundly into the eye and can cause retinal damage.
