उत्तर
Most of the refraction of light takes place in the cornea.
Explanation:
Most of the refraction of light entering the eye occurs at the outer surface of the cornea because of the large difference between the refractive index of air and that of the cornea. The pupil is merely an aperture, and the iris controls the size of the pupil.
