A retinal condition known as photoretinopathy occurs in people who have stared fixedly at the sun without adequate protection, usually for more than a few minutes (see references [1]). Photoretinopathy is photochemical damage caused by visible light, especially in the wavelength region of approximately 400–500 nm (Fig. 1). Light in this wavelength region appears blue to the eye and therefore is called blue light.
