Which one of the following statements is not correct?

Human eye is a refracting system containing a diverging lens.

The retina of the human eye contains millions of light sensitive cells, called rods and cones, which convert the light into electrical messages.

Every image that is focused on the retina is upside down.

We need both eyes to judge the relative positions of objects accurately.

Explanation:

Human eye is a refracting system containing a converging lens.

Refraction is the phenomenon which makes image formation possible by the eye as well as by cameras and other systems of lenses. Most of that refraction in the eye takes place at the first surface, since the transition from the air into the cornea is the largest change in index of refraction which the light experiences.

A convex lens is also called a converging lens because it makes parallel light rays passing through it bend inward and meet (converge) at a spot just beyond the lens known as the focal point.
