Dangers of visible light waves
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. WebULTRAVIOLET LIGHT FROM OUR SUN. The Sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B, and UV-C. These are the classifications most often used in Earth …

WebIntense visible light particularly approaching UV or 'blue light' wavelengths, passes through the cornea and lens and can dazzle and, in extreme cases, damage the network of optically sensitive nerves on the retina. Wavelengths of visible light approaching the infrared have slightly different effects but can produce similar symptoms. WebThe light you see has a wavelength within the range of about 380 nm to 780 nm and a frequency range of about 405 THz to 790 THz. The human eye can suffer from retinal injury due to overexposure to visible light. Although some damage can heal, more serious overexposure to visible light may lead to permanent eye damage or even blindness.
