The bright light stimulates the photosensitive cells in the patient's retina which transmit signals to the brain, where these signals are processed and interpreted as the perception of a bright light.
When a bright light is shone into the patient's eye, the light-sensitive cells in the retina at the back of the eye convert the light into electrical signals that are then transmitted to the brain through the optic nerve. The brain then processes these electrical signals, interpreting them as a perception of the bright light.
