The question is not worded clearly, but one possibility is a set of muscles which change the shape of the lens so that you can focus on objects both near and far. As we age new layers of cells are continually being added to the lens, resulting in thickening and stiffening, so the muscles that change its shape become less and less effective.
What else can I help you with?
What shape are the lens inside your eyes?
convex
What shape is the lens in your eyes?
convex shaped or biconvex
Why do you need convex lens in eye instead of concave?
we need convex lens in eyes as convex lens bulges out and thus focuses the outside light rays at a particular point in our eye, so then only we are able to see.
How does a convex lens fix eye problems?
A convex or converging lens can fix eyes with long sighted vision. A person who is long sighted cannot focus on near objects which can be corrected by wearing a convex lens.ÊÊ
What kind of lens does a projector use?
projector have concave or convex
Why is a convex lens called a converging lens?
when a beam of light is passed through the convex lens it converges the beam of ligth.hence convex lens is called a converging lens.

Is the human eye has a double convex or a plano convex lens?
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
Which of the following lenses is a converging lens A double-convex lens B spherical-convex lens C plano-concave lens D convexo-concave lens?
Double-convex lens
What is another name for a convex lens?
Concave and convex can refer the types of lenses used to treat refractive errors in the eyes. Concave is another word for myopic lens and convex is another name for a hyperopic lens also known as nearsighted and farsighted respectively
What do convex lens look like?
Convex lens curve outwards.
