Your prescription (Rx) provides us with your doctor's recommendation for clear and comfortable vision. Please review your information with our samples below. This represents different ways of writing the same prescription:

Astigmatism correction (cylinder): Some doctors write their prescriptions in plus (+) cylinder and some in minus (-) cylinder. They are not the same. Take special note of this when entering your prescription later. If you don't see anything there, leave it blank.

Distance (dist) is often abbreviated D.V.

Reading (reading) is often abbreviated

Doctors will sometimes write the reading prescription separately, in its entirety (as "NEAR" or "N.V." or "N.V.O."). If this is the case, enter the power in the BOTTOM half of the form (you'll see; it's easy), and leave the ADD power blank ("0.00").

• Your doctor may use a blank Rx pad, not a pre-made Rx pad for eyeglasses only. If this is the case, you can draw imaginary grid-lines to separate the numbers. It will separate the different values more easily for you. The top power is always the right eye & the bottom power is always the left.
• If you don't see numbers in some of the boxes (if there is no CYL or AXIS or ADD), leave those values blank when ordering. If you only see one number for each eye, it's the "SPHERE" power; leave all the other fields blank.
• It is common for the doctor to sometimes leave out the decimal points. If you see a number like -25 or +175, it is understood that your doctor means -0.25 or +1.75, respectively. Also, an axis of 5 (or 05) is the same as 005; 90 is the same as 090. It's like using abbreviations or writing in short-hand.
• If you have no astigmatism in one or both eyes, your doctor may just write the sphere power alone, or may use placeholders like sph ("sphere") or D.S. ("diopters sphere") instead.
• If you have a prescription for bifocals, and you only see one ADD power, it's understood that you have the same ADD for both eyes. If you don't see an ADD power, leave it blank.

If you feel you still don't understand your prescription contact us to ensure everything is entered correctly. We want to be sure your glasses that you order are made exactly to your doctor's specifications for you comfort and eye care.
