Types of Prescriptions
Standard Grid Format
This is the most common format with clearly printed fields for OD, OS, SPH, CYL, etc.; values are usually entered with a computer but may be handwritten by a doctor.
Rx Notes: |
Sphere (SPH) and Cylinder (CYL) always have a (+) or (-) sign. On any prescription, PD can be written in different ways: e.g., 62 (Single PD), 33/31 (Dual PD), or 62/60 (Distance PD/Near PD). |
Progressive / Bifocal
For multi-focal glasses, as well as reading and computer glasses, your Rx will include an ADD or NV value. This number always has a (+) sign.
Rx Note: |
The type of Rx glasses may be noted on a prescription, such as DV [Distance Vision/nearsightedness] and NV [Near Vision/reading]. |
Prescription with Prism
The less common prism Rx refers to the amount of prismatic power needed to compensate for eye alignment issues (e.g., double vision or “lazy eye”). The prism Rx will have two values: PRISM & BASE.
Rx Note: |
BO=Base Out, BI=Base In, BU=Base Up, and BD (or BDn)=Base Down. |
