Question

Find the power of the eye lens when ciliary muscles are (1)fully relaxed
(2)in their maximum contract position

Answer 1

Answer:

1. The power is zero and eye-lens is thin when ciliary muscles of the eye are in their most relaxed state.

2. When the ciliary muscles contract, they loosen the ciliary fibers which are attached to the envelope of the crystalline lens. Because the lens is pliable, it relaxes into a more curves shape, increasing it's refractive power to accommodate for closer viewing.
