PHY 104 The Human Eye Objective Question

Question

A person with hyperopia (farsightedness) needs to bring distant objects into sharp focus on their retina. What type of corrective lens is used for this condition?
Options
A A diverging (concave) lens.
B A cylindrical lens.
C A converging (convex) lens.
Correct Answer
D A prism lens.
Correct Answer

Option C is the correct answer.

Detailed Explanation

For presbyopic or hyperopic eyes, which form images beyond the retina, 'To correct this defect, a converging lens is used to focus the image on the retina'. Converging lenses add power to the eye's system, helping to focus light sooner.

Hint

Hyperopic eyes focus light behind the retina, so a lens that converges light is needed.
