Where do light rays experience more refraction – on the surface of the cornea or on the surface of the lens?

The lens has a relative refractive index of about 1.44, while that of the cornea and anterior chamber fluid is about 1.34. Consequently, the lens refracts light slightly. Light rays experience significant refraction on the outer surface of the cornea, i.e., when passing from air to the cornea of the eye.
