UV protection is critical to eye health
Eye exposure to ultraviolet rays can cause damage your eyes. Over time, UV can contribute to serious age-related eye conditions or diseases. That’s why wearing lenses with maximum UV protection is so very important. Because UV rays are always present outdoors—on sunny days, cloudy days and every day in between.
Unlike sunscreen that you apply and reapply, eyeglass lenses and sunglasses can have ultraviolet protection built into the lens, or applied as a lens treatment. Remember, although UV is invisible to the human eye, it is always present. Your lenses, therefore, should always provide UV protection.
The most important thing you need to know about UV glasses is this: Be certain your eyewear provides near or exactly 100% UV protection against both UVA and UVB rays. Anything less is less than ideal for the short and long-term protection of your healthy sight.
