Power of Accomdation of the Eye :


↪ The Ability of Eye lens to adjust it's Focal Length with the help of Ciliary muscles. This Process is known as "Power of Accomdation of the Eye".


✏ Conditions of Ciliary muscles:

First Case : ↪ When the Ciliary muscles are, in relaxed Position then the eye lens becomes thin and length of Focus has increased and resultant in Distant objects gets Visible in our Eyes.


Second Case : When the Ciliary muscles are , in Contract Position then the eye lens becomes too thick and the focal length has decrease and resultant in Near By objects get Visible in our Eyes.
