PHY 104 The Human Eye Objective Question

Question

To correct myopia (nearsightedness), what type of lens is typically used?
Options
A A converging (convex) lens.
B A diverging (concave) lens.
Correct Answer
C A cylindrical lens.
D A bifocal lens.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states: 'Similarly, correcting a myopic eye involves using a diverging lens to create a sharp image on the retina.' Myopia causes distant objects to focus in front of the retina, so a diverging lens is needed to spread the light rays before they enter the eye.

Hint

Myopic eyes focus light too strongly, so a lens that spreads light is needed.
