How are we able to see nearby and also the distant objects clearly?

Answers (1)

Ans.
Human eye has an eye lens to adjust its focal length. This is known as power of accommodation.
We are able to see nearby and also the distant objects clearly due to this power of accommodation of the eye.
When the muscles are relaxed, the lens becomes thin and its focal length increases.
When the muscles are contracted, the lens becomes thick and its focal length decreases.
This enables us to see the distant as well as nearby objects clearly.
This is what makes eye to see different objects at different distances clearly.
