Question

When ciliary muscle of a normal eye is in most contracted state? Explain with reason

Answer 1

Dear Student,
(a) for most relaxed and (b) for most contracted state
a) the size of lens is larger thus the focal length is more & the curvature if lens is less. and power is inversely proportional to focal length
b) vice versa of (a). the size of lens decreases thus the focal length is less.
