Definition of a Sphere A sphere is a geometrical figure that is perfectly round, 3-dimensional and circular - like a ball. Geometrically, a sphere is defined as the set of all points equidistant from a single point in space.
SPH = SPHERE-The amount of long or short sightedness. This value specifies the optical power of a lens in diopters. It always has a plus (+) or a minus (-) sign in front or above it. There will always be a value for sphere, even if it is just zero (written as 0.00, Plano or P). If the vision in one eye is very poor, the word 'balance' or 'bal' may be written.
