Question 6

Figure 1 shows how light rays focus in two different vision defects, Diagram A and Diagram B.

Figure 1: Two diagrams illustrating vision defects. In Diagram A, incoming parallel light rays pass through the lens and converge to a focal point in front of the retina. In Diagram B, incoming parallel light rays pass through the lens and converge to a point behind the retina.

Describe the causes of the vision defects shown in Diagram A and Diagram B.

Use information from Figure 1 to help with your answer.
