Question 58

An optometrist can diagnose long-sightedness (hyperopia) by testing a patient's near vision. Below is a simplified diagram representing how light is focused in a long-sighted eye when looking at a close object.

A simplified diagram of a long-sighted eye showing rays of light from a near object passing through the cornea and lens. The light rays converge and focus at a point behind the retina.

Give one biological reason why some people are long-sighted.
