A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
convex lens
A convexo-concave lens is a lens that has one side convex (outward bulging) and the other side concave (inward curving). This type of lens can be used to correct myopia (nearsightedness) by diverging light rays entering the eye.
A concave lens is a lens that is thinner at the center and thicker at the edges. It is used to correct myopia (nearsightedness) by diverging light rays before they enter the eye, thus helping to focus the image on the retina. Concave lenses are often used in glasses or contact lenses for people with nearsightedness.

Diverging lens is another name for a concave lens. It is thinner at the center than at the edges and disperses light rays outward.
A concave lens will be thinnest at its center.
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
A convex lens acts as concave lens when it is kept in a medium whose optical density is higher than the lens itself. And the vice-verse is also true .i.e, a concave lens can act as convex lens too .

CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.
