Knowledge about sphere:
The term "sphere" comes from the pure mathematics of lenses. Lenses derive their power from incurved surfaces. A spherical lens has constant curvature in each direction perpendicular to the optical axis. Spherical lenses square measure adequate correction once someone has no astigmatism. To correct for astigmatism, the "cylinder" and "axis" elements specify however a selected lens is completely different from a lens composed of strictly spherical surfaces.
