Introduction
Your eyeglass prescription is the key to clear vision, but the numbers and abbreviations can feel like a secret code. Whether you’re shopping for new frames at phifinery.com or simply curious about your eye health, understanding your prescription empowers you to make informed choices. In this guide, we’ll break down every part of your prescription, explain common terms, and show you how phifinery crafts lenses tailored to your unique needs.
What’s in Your Prescription? Breaking Down the Basics
Eyeglass prescriptions include measurements for each eye, corrections for specific vision issues, and details about lens type. Here’s what to look for:
- OD and OS: Which Eye Is Which?
- OD (Oculus Dexter): Your right eye.
- OS (Oculus Sinister): Your left eye.
- Some prescriptions include OU (Oculus Uterque), meaning both eyes.
Pro Tip: Always double-check these abbreviations to ensure your lenses are made correctly!
- Sphere (SPH): Correcting Nearsightedness and Farsightedness
- A “-” sign means you’re nearsighted (trouble seeing far away).
- A “+” sign means you’re farsighted (difficulty focusing up close).
- The number indicates lens strength (e.g., -2.50 or +1.75).
- Cylinder (CYL) and Axis: Fixing Astigmatism
- CYL measures how much lens power is needed to correct an irregularly shaped cornea.
- Axis (0–180 degrees) shows where the astigmatism correction is applied.
- Add: Multifocal Lenses for Reading
- Found in bifocal or progressive prescriptions, the “Add” value (always a “+” number) boosts magnification for close-up tasks.
- Prism and Base: Rare but Important
- Corrects eye alignment issues (e.g., double vision). The “Base” direction (up, down, in, out) tells where the prism’s thickest edge sits.
