Don’t Take the Sun Lightly: *
Certain types of light from the sun can wreak havoc in the eye area.
Ultraviolet A and Ultraviolet B light: *
Long-range, ultraviolet A (UVA) and short-range, ultraviolet B (UVB) rays are the most dangerous forms of light produced by the sun. At 320-400 nm (nanometers, or billionths of a meter) and 290-320 nm, respectively, these powerful rays have wavelengths shorter than visible light, making them invisible to the naked eye. They are considered a major cause of cataracts, eyelid cancers and certain other skin cancers, and believed to play a part (along with high-energy visible light, which includes blue light, part of the visible light spectrum) in macular degeneration, one of the major causes of vision loss in the U.S. for people over age 60. In addition, UV rays can prematurely wrinkle and age the skin around the eyes.
High-Energy Visible Light (HEV light) / Blue Light: *
Some of the latest eye research has implicated HEV light – high-energy visible light in the violet/ blue spectrum – as a contributor to the development of cataracts, macular degeneration and other serious eye maladies. HEV falls into the near-UV range, from almost 400 to over 500 nm in the visible spectrum. Blue light, roughly between 440 and 490 nm within the HEV spectrum, can damage the retina over time, leading to macular degeneration. The retina is the ocular membrane where images are formed and transmitted to the brain; the macula, the region of sharpest vision located near the center of the retina, is the most likely area to be damaged.
Truly Unique Lenses
Coppertone® Polarized Lenses block 100% of harmful UVA and UVB rays and offer more protection (160% or more) from High-Energy Visible (HEV) light than ordinary sun lenses, an important way to help keep eyes healthy into old age.
