Overexposure to UVA radiation has been cogitate 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 at heart the realm of visible l! ight. In the electromagnetic spectrum, radio waves have the lowest energy, and da Gamma rays have the highest energy. As the pull in 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.
