Question 8

Figure 1 shows how light rays from an object are focused by a healthy eye.

Figure 1: Diagram showing light rays originating from an object, passing through the curved cornea where they are refracted, and then passing through the lens where they bend further to converge exactly at a point on the retina at the back of the eye.

Describe how the structures in the eye focus these light rays to form a clear image on the retina.
