Curvature radius refers to the focal length of the lens. The focal length of each side of the lens depends on the curvature of the lens surface.

In fact, the focal length of that side is simply the the radius from the optical centre to the centre of the circle drawn from the surface! In the example above, it is also shown that focal length of each side of converging lens may be different if the sides are not identically curved.
