Power of a lens is the ability of a lens to converge (or diverge) a parallel beam of rays parallel to its axis.  The tangent of the angle of deviation of the  refracted ray from the incident ray is called the power.

   Power of a lens P = 1/f     where f = focal length in meters.
 
   so f = 1/P     where P is expressed in Diopters.
