Question

The curvature of the eye lens of the human eye:

• A. is fixed
• B. can be increased
• C. can be decreased
• D. increases or decreases as the case may be

Hint:

The ciliary muscles control the curvature of the eye lens to focus light on the retina for clear vision at various distances.

Answer 1

The Correct Option is D

The curvature of the eye lens is controlled by the ciliary muscles. When these muscles contract or relax, they change the shape of the lens, which in turn affects the focusing ability of the eye.
- The curvature of the lens increases to focus on nearby objects and decreases to focus on distant objects. Thus, the correct answer is (D) increases or decreases as the case may be.
