When light enters your eyes, it passes through the cornea, which helps focus the light. The light then moves through the lens, which further focuses it onto the retina at the back of the eye. The retina contains light-sensitive cells called photoreceptors that convert the light into electrical signals to be sent to the brain via the optic nerve for processing.
