WebOct 26, 2024 · The eye lens is a flexible transparent membranous structure. We can modify the curvature of the eye lens through contraction and relaxation action of the ciliary muscles. The modified curvature changes the focal length of the lens. When the ciliary muscles are relaxed, the lens membrane becomes thin that increases its focal length. cryptogamic garden upsc
