Question

How does the change in curvature of the eye lens help us in the process of seeing the nearby objects clearly?

Hint:

Nearby object → Lens becomes thicker → Focal length decreases.

Answer 1

Explanation:

• To see nearby objects, the ciliary muscles contract.
• This increases the curvature (thickness) of the eye lens.
• The focal length of the lens decreases.
• As a result, the image of the nearby object is formed clearly on the retina.
