Vedclass · Answer

(C) When a sudden bright light falls on the eyes,the photopigments (like rhodopsin in rods and iodopsin in cones) undergo rapid photobleaching or chemical breakdown.This process temporarily depletes the available pool of functional photopigments in the retina.As a result,the photoreceptor cells cannot immediately generate a new visual nerve impulse until the pigments are resynthesized.This brief period of blindness or 'glare' is due to the time required for the regeneration of these photopigments.
