Everyone enjoys a sunny day. For example, a light amber-colored lens can provide the same UV protection as a dark gray lens. While many people refer to ultraviolet radiation as "UV light," this term technically is incorrect because you cannot see UV rays. With this in mind, it's especially important for kids to protect their eyes from the sun. While UVB light primarily damages the genetic material, UVA rays penetrate deeper, cause thermal damage and magnify the effects of UVB light. Also, children are more susceptible to eye damage from UV rays because the lens inside a child's eye is clearer than an adult lens, enabling more UV to penetrate deep into the eye. In the electromagnetic spectrum, radio waves have the lowest energy, and gamma rays have the highest energy. Although shade reduces your UV and HEV exposure to some degree, your eyes still will be exposed to UV rays reflected from buildings, roadways and other surfaces. Setting: UV exposure generally is greater in wide open spaces, especially when highly reflective surfaces are present, like snow and sand.

But this also means depletion of the ozone layer potentially could allow high-energy UVC rays to reach the Earth's surface and cause serious UV-related health problems.

UVC rays have wavelengths that range from 100 to 280 nanometers (nm). You probably know that too much exposure to the sun's ultraviolet (UV) rays can cause sunburn and skin cancer. What happens to FSA dollars at the end of the year? Overexposure to the sun's UVB radiation also is associated with a number of eye problems, including pinguecula, pterygium and photokeratitis ("snow blindness").

Your eyes need protection even on cloudy days because the sun's damaging UV rays can penetrate cloud cover. But this also means depletion of the ozone layer potentially could allow high-energy UVC rays to reach the Earth's surface and cause serious UV-related health problems. UVB rays have slightly longer wavelengths (280-315 nm) and lower energy than UVC rays. What do the numbers on your eyeglass frames mean?
