The bright light stimulates the photoreceptor cells in the patient's retina, which then send electrical signals to the brain to be interpreted as visual information.
When a bright light is shined into a patient's eye, the light enters the eye and stimulates the photoreceptor cells in the retina. These cells then convert the light into electrical signals that are transmitted to the brain via the optic nerve, allowing the brain to perceive the bright light.
When the eye doctor shines a bright light into the patient's eye, the light enters the eye through the pupil and reaches the retina, where photoreceptor cells called rods and cones convert the light into electrical signals. These signals then travel through the optic nerve to the brain, where they are interpreted as a perception of the bright light.
