Sphere (SPH): Indicates the lens power for near- or farsightedness. A minus (-) number is for nearsightedness, and a plus (+) number is for farsightedness. Cylinder (CYL): If you have astigmatism, this value corrects it. Leave blank if not applicable. Axis: For astigmatism correction, this specifies the orientation of the cylindrical power. This is a number between 1 and 180 degrees. ADD: The additional magnifying power for reading (used in multifocal or bifocal lenses). This is often the same for both eyes.
