A prism has 3 flat faces while a convex lens has two curved faces. However the edge of a convex lense has a similar geometry to two adjacent faces of a prism.

A convex lens is thicker in the center than at the edges. A convex lens is like a concave mirror.A concave lens is thinner in the center than at the edges.
A convex lens is thicker in the centre than the outsides. A concave lens is thinner in the centre than the outsides.
The edges of a convex lens are thicker than the middle.

The edges of a convex lens are thicker than the middle.
In a convex lens, the middle is thicker than the outer rim. In a concave lens, the outside rim is thicker.
Concave is thinner in the center than the edges and convex lens is thicker in the center than on the edges :)
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 .
