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.
The convex lens bulges out at the center, while the concave lens bulges in at the center. The convex lens magnifies, while the concave lens reduces.

A convex lens magnifies.
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
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 .
