What do Contact Lense Prescription Signs Mean?
The indications in a contact lens prescription may be confusing to you and difficult to interpret, so let’s first get a thorough understanding of them.
- OD And OS
Oculus dexter, the Latin word for the Right Eye, is abbreviated as OD, and Oculus sinister, the Latin word for the Left Eye, is abbreviated as OS. So, simply keep in mind that OS is your LEFT eye, and OD is your RIGHT eye. Sometimes the letters OU will appear on your prescription. These stand for “oculus uterque” or “EACH EYE,” which denotes that the same evaluation relates to both.
- PWR
Refractive power is discussed in PWR. SPH is another name for this at times (sphere.) This is the amount of correction—measured in diopters, an optical unit—necessary to get your vision as close to perfect 20/20 as feasible. The prescription gets stronger the further it is from zero. Different prescriptions for each eye are quite common.
- BC
The base Curve, which is measured in millimeters, is the contact lens back curvature. Typically, this number falls around 8 and 10. Due to its compatibility with your cornea’s curvature, this value is crucial for the fit of your contacts. The main reason your prescription doesn’t have a base curve is that your lenses’ manufacturer only offers one base curve.
- DIA
The dimension of a contact lens is its width across its surface, expressed in millimeters. The location of the contact lens on your eye is determined by this number, which is often between 13 and 15. The contact lens would be unpleasant and may irritate your eye if this dimension is incorrect.
- OU
This is an initial for the Latin phrase Oculus uterque, which translates to “two eyes.” Therefore, your physician may use the word OU rather than OD and OS if both of your eyes require lenses of the same prescription.
- ADD
For those who want bifocal contact lenses, an extra assessment called Add power, or ADD, is necessary. This shows how much magnification the lens has to have to see up close.
- Brand
Your doctor might advise you to wear a certain brand or kind of contact lenses. Your doctor will recommend the brand that is ideal for your eyes because various brands employ a wide range of materials and can have particular special qualities.

- Hybrid Contact Lenses
