Need glasses? Your eye doctor or optician has provided you a prescription but are you finding it difficult to understand? Well, if you want to select and order the right pair of glasses for your eyes, you need to understand the prescription first. Don’t worry we will assist you in understanding your prescription.
Here are examples of usual prescriptions written by the doctors:
- D.V. is shorthand for "Distance Vision" (Farsighted)
- N.V. is shorthand for "Near Vision" (Nearsighted)
- OD actually means "Right Eye"
- OS actually means "Left Eye"
- OU means "Both Eyes"
- CYL indicates "Cylinder"
- PD means “Pupillary Distance”
- AX or X indicates "Axis"
- Astigmatism means an optical condition that causes blurry vision
Single vision prescription
These glasses are usually prescribed to people with difficulty in seeing objects at a distance, reading or computer (Any one).
Bifocal vision prescription
These glasses are usually prescribed to people with difficulty in seeing objects at a distance and reading or reading and computer.
Progressive/Multifocal/Varifocal vision prescription
These glasses are usually prescribed to people with difficulty in seeing objects at a distance and reading or reading and computer but they do not have lines on the lenses like bifocals.
- Your astigmatism correction ("cylinder"): Some eye-specialists write their prescriptions in plus (+) cylinder and some in minus (-) cylinder. Remember both are different. Make sure you consider this point when you enter your prescription. If you don't see anything there, leave it blank.
- Usually doctors forget to put decimal points between the numbers. For example if the number is - 25 then it should be interpreted as 0.25 or if it is +175 then the doctor means +1.75.
