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.
Or you can answer :
The cornea is the transparent part of the eye that covers the front portion of the eye. It covers the pupil (the opening at the center of the eye), iris (the colored part of the eye), and anterior chamber (the fluid-filled inside of the eye). The cornea's main function is to refract, or bend, light.
An object that starts and ends at the same point would have zero displacements.
<h3>What is displacement?</h3>
Displacement is the property of a body or an object to be moved from one place to another.
Thus a body that moves or is moved from point A to point B has been displaced.
A body with zero displacements either did not move at all or finished at the same point it started.
For example, a body that moves from point A to B, and then back to A will have zero displacements.
