Question

What is cornea ? What is its functions

Answer 1

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.

Explanation:

The cornea is the eye's outermost layer. It is the clear, domeshaped surface that covers the front of the eye. It plays an important role in focusing your vision.Because transparency is of prime importance the cornea does not have blood vessels; it receives nutrients via diffusion from the tear fluid at the outside and the aqueous humour at the inside and also from neurotrophins supplied by nerve fibers that innervate it.
