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.
