Prescription requirements

  • Make sure your prescription contains:
    • Prescription information for both your right and left 
    • Pupillary Distance (PD) number. Pupillary Distance is the distance (in millimeters) between the center of your pupils.
    • Fitting height (This applies only to Fit to Your Frames orders of progressive lenses.)
  • Your prescription should be within these ranges:
    • Single Vision: SPH -4 to +3 CYL -4 to +4
    • Progressive: SPH -4 to +3 CYL -4 to +4 ADD +1 to +3
  • Your prescription must be current. Most prescriptions need to be renewed every two years. Also, be sure that your prescription is signed by your doctor.

Pupillary Distance (PD)

Pupillary Distance, also called PD, is the distance in millimeters between the center of your pupils. Usually it is a number between 50-80 mm. It can also be written as the 1/2 PD (half-PD) which is two numbers, each number typically between 25-40 mm.

Often, doctors do not write the PD on their patient’s prescription. However, in many locations, doctors are required by law to provide patients with the PD if they request it. Next time you get your prescription updated, remember to ask your doctor to include the PD.

Fitting Height (FH)

Fitting Height (FH) is the vertical measurement in millimeters from the most bottom edge of your lenses to pupil center. Fitting height only applies to Fit to Your Frames orders with progressive lenses.

Out-of-range prescriptions

Out-of-range prescriptions might be possible, depending on the geometry of your frames, your prescription and PD. If you want to find out if we can make your prescription, email us at rx@enchroma.com. If your prescription power is complex or has a very high power, we’ll contact you to discuss your options.
