PHY 104 The Human Eye Objective Question

Question

A presbyopic or hyperopic (far-sighted) eye forms images beyond the retina. Which type of corrective lens is used to bring the image onto the retina?
Options
A A diverging lens
B A converging lens
Correct Answer
C A cylindrical lens
D A bi-focal lens (only as a combination)
Correct Answer

Option B is the correct answer.

Detailed Explanation

The text indicates, "To correct this defect [presbyopic or hyperopic eye], a converging lens is used to focus the image on the retina."

Hint

These conditions involve light focusing too weakly, so a lens that brings light together is required.
