Blue-light hazard is the potential for photochemically-induced retinal injury resulting from electromagnetic radiation-exposure at wavelengths primarily between 400 and 450 nm. Researchers have not studied the phenomenon in humans, but only (and inconclusively) in some rodent, primate, and in vitro studies. Photochemically-induced retinal injury is caused by the absorption of light by photoreceptors in the eye. Under normal conditions, when light hits a photo… WebThe absorption intensity is weaker than for the fundamental vibrations, but this is not important as longer path-length cuvettes can be used.
