The power of the concave lens is considered to be negative.
“The power of the lens is referred to as the reciprocal of a lens's focal length.” Focal length is considered positive for the convex lenses and negative for the concave lenses. Since the focal length of concave lenses is negative, the power of concave(diverging) lenses is taken as negative.
