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 ciliary muscles adjust the eye's lens curvature, which governs focus. Lens shape changes with muscle action:
- Curvature increases for near vision and decreases for far vision.Therefore, the correct choice is (D), reflecting the curvature's variability.
