Maximum contribution to the refractive power of the eye is by which pa of the eye?
(A) Anterior surface of cornea (B) Posterior surface of cornea (C) Anterior surface of lens (D) Posterior surface of lens
(A) Ans: A. Anterior surface of cornea Maximum contribution to refractive power of eye - By anterior surface of cornea.Cornea's anterior surface is approximately spherical with a radius of curvature that is typically 8 mm.This surface is responsible for about two-thirds of the eye's refractive power.
