Question 28

Figure 1 shows parallel light rays entering the eye of a person with a vision defect. It also shows two lenses, Lens A and Lens B, which are used to correct vision defects.

Figure 1: Diagram showing light rays entering an eye and converging at a focal point behind the retina, indicating hyperopia (long-sightedness). Below the eye diagram are two corrective lenses: Lens A, which is a bi-concave (diverging) lens, and Lens B, which is a bi-convex (converging) lens.

Explain which lens, A or B, would correct the eye defect shown in Figure 1.
