The dioptry (D) is a unit of measure for the refractive power of a lens.
The power of a lens is measured in diopters, which are the reciprocal of the focal length in meters.
A positive diopter indicates a converging lens, while a negative diopter indicates a diverging lens.
The higher the diopter value, the stronger the lens.
