- SPH stands for Spherical, refers to the refractive correction in the prescription. Minus (-) are for near sightedness, and Plus (+) values are for far sightedness.
- CYL stands for Cylinder, refers to the strength of the correction for the astigmatism in the eye. It can be either positive or negative.
- AXS, or Axis, refers to the angle of the correction for the astigmatism in the eye (if one exists) from 1 to 180.
- NV stands for "Near-Vision." This number indicates the additional magnification that is added to the distance prescription to get the reading portion of the lens in a multi-focal prescription.
- PD stands for Pupillary Distance. The distance, is in millimeters, between the center of one pupil to the center of the other.
