Optical Power

Optical power (also known as dioptric power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device in meters. A positive power indicates a converging lens, while a negative power indicates a diverging lens.

P (Diopters) = 1 / f (meters)
