How to read and understand your prescription?
The eyeglass prescriptions are typically written in a grid with scientific terms, abbreviations, and numbers. Remember, the further the numbers are from zero, the more correction you need. A+ symbolizes farsightedness and, A- which represents nearsightedness. Other abbreviations are:
- OD – Oculus Dexter, which means right eye.
- OS – Oculus Sinister, which means left eye.
- SPH (Sphere) – Eyeglass prescription power.
- CYL (Cylinder) – Astigmatism is an imperfection in the curvature of the eye.
- AXIS – Degree and direction of your astigmatism need correction.
(Cylinder and Axis go together as this is the corrections for your astigmatism) - ADD – Add Power is the magnifying power in the lower part of a multi-focal lens. (ADD power is not needed for single vision distance eyewear.)
