How to read your eyeglasses prescription
At first glance your eyeglasses prescriptions might look like a bunch of confusing numbers, symbols and abbreviations. Here is a guide to help you understand this information.
Your prescription might look like this:
Reading your prescription:
o O.D. & O.S. tells you which eye the prescription refers to. “O.D.” is the right eye and “O.S.” is the left eye.
o SPH: a nearsighted or farsighted “spherical error”. A “-“means that the prescription is nearsighted, A ”+” means that your prescription is farsighted. The higher the number, the stronger your prescription.
o CYL & AXIS: these numbers describe your astigmatism. The “CYL” number shows the severity of the astigmatism. Axis indicates which way the astigmatism is oriented.
o ADD: this number is only used for bifocals and is added to the sphere prescription to get the near vision prescription.
o PD: is the pupil distance. If you don’t not know your P.D. than go to learn how to measure your Pupil Distance.
