It’s just what it sounds like — the distance in millimeters (mm) between your pupils. An average PD measurement in 63mm, but it varies by person. If your PD number isn’t on your prescription, you can measure it yourself by:

PD (Pupillary Distance)

Pupillary Distance

The ADD number is sometimes written NV for near vision, and is used for multifocal lenses and readers.

A cylinder value indicates astigmatisms, or perpetually blurry vision. The axis — measured between 1° and 180°— tells us the orientation of the astigmatism.

Horizontal prism correction is used to help correct lateral eye misalignments, and is always prescribed in the same direction for both eyes.

Prism correction is used to help correct diplopia, or double vision. The prism bends light to help align the vision so only a single image is seen.

Spherical error, or the overall lens power, is the basic part of your prescription. You’ll notice (+) and (-) signs on your prescription. When there’s a (+), it means you have trouble seeing near, and when there’s a (-), it means you have trouble seeing far away.

Vertical prism correction is used to help correct vertical eye misalignments, and is prescribed in opposite directions (upward in one eye, and downward in the other).
