spherocylinder prescription
A lens prescription that includes both sphere (or spherical) and cylinder (or cylindrical) components is known as a spherocylinder (or spherocylindrical) prescription. The sphere and cylinder powers of a spectacle prescription are measured in diopters (D), where the reciprocal (inverse) of the dioptric power equals the focal length, in meters, of that portion of the lens.
