Blue and Ultraviolet Light
Blue and ultraviolet light can cause damage to the eyes. The portion of the invisible light spectrum between 286 nm and 400 nm is regarded as hazardous to the eyes, as it can cause significant eye conditions such as cataracts and macular degeneration.
The retina is vulnerable to this light, and depending on the wavelength, intensity, and duration of exposure, three forms of retinal damage can be observed, including structural thermal and photochemical.
The sun and other sources, such as fluorescent lighting, video display terminals, and welder’s flash, can emit UV radiation. The photons emitted by sunlight can cause damage to the eyes if they are exposed to an excessive amount.
