Your eyes need light to see because light reflects off objects and enters the eye through the cornea, pupil, and lens, which focus it onto the retina. The retina contains photoreceptor cells that convert the light into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are interpreted as images. Without light, there is no information to process, making vision impossible.
