When the eye doctor shines a bright light into the patient's eye, the light enters through the cornea and lens, focusing on the retina at the back of the eye. The retina contains photoreceptor cells, which convert the light into electrical signals that are transmitted via the optic nerve to the brain, where the visual cortex processes the information, allowing the patient to perceive the brightness and location of the light.
