The patient's brain perceives the bright light due to the activation of photoreceptor cells in the retina that send electrical signals to the brain, which then processes and interprets these signals as visual information.
is this correct?
Yes, that is correct.
When the bright light enters the patient's eye, the light-sensitive cells in the retina called photoreceptors detect the light and convert it into electrical signals, which are then transmitted to the brain via the optic nerve, allowing the brain to perceive the bright light.
