Base curve
Base curve radius or simply base curve, abbreviated BCR or BC, is the measure of the general shape of a lens in optometry. On a spectacle lens, it is the flatter curvature of the front surface and on a contact lens it is the curvature of the back surface. Typical values are from 8.0 to 10.0 mm. The base curve is the radius of the sphere of the back of the lens that the prescription describes. Lenses must fit well to the wearer's cornea in order to be comfortable and to facilitate tear exchange and oxygen transmission.
Diameter
Diameter of the lens, short DIA. Typical values are from 13.00 to 15.00 mm.
Sphere
Spherical correction, or diopter, abbreviated DPT, D or SPH is a unit for measuring the optical power of the lens. Typical values are between 20.00 and -20.00.
In myopia speak of negative diopters and hyperopia in the positive.
Cylinder
Cylindrical correction abbreviated CYL used in toric contact lenses to correct astigmatism. Тypical values are from +6.00 to -6.00.
