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

A double-convex lens is a type of lens that is thicker in the middle and thinner at the edges. It converges light rays to a focal point on the opposite side of the lens. This type of lens is commonly used in magnifying glasses and camera lenses.
Diverging Lens are use (reading glasses) to help correct the problem of myopia helping fix the focus which causes items far away to seem fuzy and blurry.
It is done in following ways: 1. By placing a proper(convex or concave etc.) lens with an apt value of focal length so that the final image is obtained exactly on the retina. 2. For very distant or small images two lenses are used with fix value of focal length. Among these two one lens is movable. So by shifting position of one lens we can get a sharp image of object. 3. Naturaly our eye lens are connected to various nerves which either by compression or expansion allows our eyes to focus. Yes in this process the thickness of our eye lens(natural) changes.
