Standard Grid Format
This is the most common format with clearly printed fields for OD, OS, SPH, CYL, etc.; values are usually entered with computer, but may be handwritten by 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). |
