Power of lens is an expression which is used to denote the converging and diverging power of that lens.
It is defined as 1/f
where f is the focal length of lens in m
Mathematically you can consider it as the tangent of the angle of conergence or divergence of a ray of light parallel to the principle axis falling 1 m away from the center.
