Answer:
HI MATE !
Concave lens surfaces have a virtual and therefore negative radius of curvature.
The convention signs used for focal length are also used for optical power.
Convex lenses, which have a real focus, have a positive focal length and optical power.
Concave lenses, with a virtual focus, have a negative focal length and optical power.
The power of concave lenses is always negative.
