Strictly speaking, Bendigo is right. The eye has a lens within a lens. The curvature of the cornea means that it behaves as a focusing lens of fixed power. The internal lens allows for accommodation.
Together with the lens, the cornea refracts light, accounting for approximately two-thirds of the eye's total optical power.
I remember one of the Russian pioneers in the old methods of refractive surgery. Drove a Rolls and undoubtedly made a fortune. That would have been well over 20 years ago using primitive methods by today's standards I suspect.
