how is focusing of eye done by ciliary
muscle?
Answers
It is the second part of your eye, after the cornea, that helps to focus light and images on your retina. ... The lens provides 25-35% of your eye's focusing power. The ciliary muscles, which are part of the ciliary body, are attached to the lens and contract or release to change the lens shape and curvature
The main function of the ciliary muscles used to change the shape of the lens in the eye to help with focusing. Another function of the ciliary muscles is to help regulate the flow of aqueous humor in the eye.
The ciliary muscles are made of layers of smooth muscle in a circular shape that helps suspend the lens. When these muscles contract, the lens curves and allows for vision up close, and when they relax the lens is able to focus on objects that are further away. It does not affect the size of the people, which is controlled by different muscles.
