WebThe eye's accommodative mechanism changes optical power for near vision. In accommodation, ciliary muscle excursion relieves lens tension, allowing it to return to … 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.
