Vedclass · Answer

(A) When a source of bright light is suddenly directed towards the eye,the pupillary light reflex is triggered. The circular muscles of the iris contract,causing the pupil to constrict (miosis). This action reduces the amount of light entering the eye to protect the retina from damage and to adjust to the increased intensity of light.
