SPH stands for Sphere, an ophthalmology & ENT abbreviation.

Column on an eyeglass or contact lens prescription giving the lens power in diopters that corrects nearsightedness (minus values) or farsightedness (plus values) equally in all directions.

Example: Glasses Rx: OD SPH -3.50, CYL -0.75, axis 090.

Usage notes

Values are written in steps of 0.25 diopters. "Plano" or "pl" means zero power. When there is no astigmatism, prescriptions write "sph" or "DS" (diopter sphere). The sphere is the largest component for most people needing glasses.
