Cortical or nuclear cataract was not associated with ocular exposure to blue or all visible radiation, rather than infrared or ultraviolet light,[4] while blue or visible light contributes to advanced AMD other than ultraviolet light.[5]Third, it is not sure whether there might be simultaneous onset of AMD and lens opacity or in an order when only take the light exposure into consideration.
At the obtained speed of light inside the sphere of the carbon atom, the wavelength of visible radiation is:
During these processes, semiconductors are irradiated with UV or visible radiation to excite electrons from the valence band (VB) to the conduction band (CB) creating electron/hole pairs.
