Answer 2

Hey mate here is the Answer:

The cornea acts as the eye's outermost lens. It functions like a window that controls and focuses the entry of light into the eye. The cornea contributes between 65-75 percent of the eye's total focusing power. When light strikes the cornea, it bends -- or refracts -- the incoming light onto the lens.

Hope it helps you..
