How to Read Your Prescription
Right Eye (OD) & Left Eye (OS)
OD stands for "oculus dexter" which is Latin for "right eye". OS stands for "oculus sinister" which is Latin for "left eye."
Sphere (SPH) aka Power (PWR)
If you’re nearsighted you’ll have a minus (-) before the number, and if you’re farsighted you’ll have a plus (+) sign.
Cylinder (CYL)
This is only for people with astigmatism. A nearsighted astigmatism will have a minus (-) before the number, and a farsighted astigmatism will have a plus (+) sign.
Axis
This is only for people with astigmatism. The axis is a number between 0 and 180 and determines the orientation of the Cylinder (CYL).
We need your Pupillary Distance (PD) to ensure that your glasses are customized to fit you perfectly. PD is the distance between the centers of each eye. Once we get your PD we can finish your glasses!
Kid PD Range: 35-65 mm.
Adult PD Range: 50-80 mm.
If your PD has 2 numbers, it is typically written 22/20 on your prescription. The first number is the right eye (OD), and the second is the left eye (OS).
