Web“blue-light” portion of the visible spectrum (380 nm to 500 nm). Our atmosphere generally protects us from UV radiation below 280 nm. Additionally, as the cornea and crystalline lens absorbs almost all natural UV radiation, UV radiation is thought to cause damage to the anterior eye, while short visible light (“blue-light”) WebSep 30, 2024 · The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. In fact, most of the light in the universe is invisible to our eyes. The light we can see, made up of the individual colors of the rainbow, represents only a very small portion of the electromagnetic spectrum.
WebDec 15, 2024 · However, up to 90 percent of the visible skin changes commonly attributed to aging are caused by the sun. With proper protection from UV radiation, most premature aging of the skin can be avoided. Cataracts and Other Eye Damage. Cataracts are a form of eye damage in which a loss of transparency in the lens of the eye clouds vision. WebPhotochemical action is a chemical change at the molecular level and is the more profound result of light exposure. The most potent sources of these destructive energies come from just beyond the limits of visible light—ultraviolet (UV) and infrared (IR) light (fig. 1). The longer wavelength, infrared, is a common source of radiant destruction.
