Plz clear d concept that when ciliary muscles r relaxed then how focal length is maximum, as when ciliary muscles r relaxed then convex lens become thick nd short due 2 which its focal length shud also b reduced??

Dear student
The eye lens is composed of fibers which makes it flexible with the help of ciliary muscles. The change in the curvature changes the focal length. When the lens becomes thin the focal length increases thus enabling us to view distant objects. When the lens becomes thick the focal length decreases and enables us to see nearby objects. This flexibility of the length is called accommodation.
We hope this clarifies your doubt.
