A convex lens is a converging lens. When parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus. The distance between the principal focus and the centre of the lens is called the focal length.
Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens.

Convex lens are thicker in the middle and thin at the edges.It bends the light ray which passed through it,inwards.It is also known as converging lens...
Concave lens are thinner in the middle and thicker at the edges.It bends the light ray passing through it,outwards and also known as diverging lens...
