Options

• can be increased.

• can be decreased.

Answer 1

The curvature of eye lens of human eye increases or decreases as the case may be.

Explanation:

The curve of the human eye lens is not constant. It varies due to the action of the ciliary muscles, which modify the focal length of the lens to concentrate on things at different distances.

• When you focus on a nearby object, the curvature of the lens increases.
• When you focus on a distant object, the curvature of the lens diminishes.
