 Blue light, also known as high-energy visible (HEV) light, has the shortest wavelength of visible light and therefore produces the highest amount of energy. As the eye is not very good at blocking blue light, virtually all visible blue light passes through the cornea and lens and reaches the retina may cause a photochemically induced retinal injury.
