To get your kids’ new eyeglasses, all you need to do is hand in their eyeglass prescription to your local optical eyewear shop. You can manage your kid’s vision-related conditions better if you have an idea of what the terms on the prescription mean. The Institute for Control of Eye Myopia, your local eye doctor, elaborates on what these terms mean below.
O.D., O.S., and O.U.
The terms O.D. and O.S., which are written under the first column, stand for oculus sinister or left eye and oculus dextrus or right eye respectively. If the prescription refers to both eyes, your eye doctor will write O.U. or oculus uterque.
This column indicates the strength of your prescription, and by extension, how bad your eyesight is. The numbers that indicate the strength of the prescription is measured in diopters. A + sign before these numbers indicate your farsighted while a – sign means your nearsighted.
If you don’t have astigmatism, a condition caused by irregularly shaped corneas, your optometrist will leave this column blank. The higher the number written under this column, the more astigmatism you have. Keep in mind that the number can either be either positive or negative.
This column indicates the extent of your astigmatism or your cornea’s curvature.
There’s a Different Prescription for Contact Lenses
Here’s another thing you should know: You can’t use eyeglass prescriptions to purchase contact lenses; you’ll need to ask for a different one from your eye doctor. Prescriptions for eyeglasses and contact lenses may use similar terms, but lens prescriptions have added information, like how long until you need to replace your contact lenses.
