What is meant by accommodation of the eye ?

Text Solution

Verified by Experts

Accommodation or power of accommodation of human eye is the ability of the eye to observe distinctly the objects situated at widely different distances from the eye.
This property is due to the action of ciliary muscles holding the eye lens.
For observing distant objects, eye is in relaxed state, i.e., unaccommodated. The eye lens is thin and image of distant object is formed on the retina.
For observing nearby objects, the ciliary muscles contract, the eye is in a state of tension. It is said to be accommodated.
