How does the eye regulate the amount of light that falls on the retina?

Advertisements

Solution

Pupil is the small aperture in the iris that regulates the amount of light entering the eye. Cornea, aqueous humour, lens, and vitreous humour act together and refract light rays, focussing them onto the photoreceptor cells of the retina
