Prolonged exposure to bright light causes retinal photopigment bleaching resulting in afterimages
Prolonged exposure to bright light bleaches retinal photopigments, which significantly reduces visual sensitivity and underlies the physiological processes of light adaptation and afterimage formation.
The retrieved literature consistently confirms that exposure to bright light causes photopigment bleaching and drives light adaptation, which relates to visual recovery and afterimages. The claim is well-supported by physiological studies on photoreceptor bleaching.
