Prescription checklist:

1. Make sure your prescription contains:

  • Prescription information for both right and left eyes.
  • Pupillary Distance (PD) number. Pupillary Distance is the distance (in millimeters) between the center of your pupils (see diagram below).
  • Fitting height (This applies only to Fit to Your Frames orders of progressive lenses).

2. 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

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.

Thinking of Giving Prescription EnChroma Glasses as a Gift?

Gifting prescription EnChroma glasses can be daunting given the need for accurate measurements and added cost. Two excellent alternatives are our EnChroma Receptor fitover sunglasses that fit conveniently over most prescription glasses. Or purchase an EnChroma Gift Card and let them select a style of their choice.

EnChroma Guarantee:

All of our EnChroma glasses with prescription lenses are covered by the same 60-day money-back guarantee and 2 year warranty as non-prescription glasses. Typical processing time is 2-4 weeks once prescription information has been received and verified.

Additional Information about Prescription Details:

Here’s an example of what a single vision prescription would look like. For single vision lenses, please be sure to provide a Pupillary Distance (PD) as defined below.

Progressive lenses require some additional information placed in the Near Vision (N.V.) or sometimes labeled ‘ADD’ boxes. ADD identifies the additional power needed for reading when a progressive lens is being ordered. Pupillary distance (PD) is needed to complete a prescription order.

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, such as 32/32, where each number is 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 Progressive Fit to Frame orders.

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.
