Question

If you are looking at the moon, then what happens to your ciliary muscles?

• A. contract
• B. expand
• C. remains in the previous position
• D. can't say

Answer 1

The correct option is B

expand

If we are looking at an infinite object then the lens has to be thin and relaxed as the rays of light are almost parallel. For lens to be thin the ciliary muscles have to be expanded (relaxed).
