How to Read Your Eyewear Prescription Like a Pro 👓
So, you’ve just received your eyeglasses prescription — and it looks like a secret code. Don’t worry! In this quick guide, we’ll help you crack it, line by line, so you can order the perfect lenses online with confidence.
🔍 A Sample Prescription
Eye | SPH | CYL | AXIS | ADD | PD |
---|---|---|---|---|---|
OD (Right) | -1.50 | -0.75 | 180 | +1.50 | 63 mm |
OS (Left) | -1.25 | -0.50 | 175 | +1.50 |
📘 What Each Term Means
- OD / OS: Latin for “Right Eye” (OD) and “Left Eye” (OS).
- SPH (Sphere): The strength of your lens. A negative number means you're nearsighted; a positive number means you're farsighted.
- CYL (Cylinder): This shows if you have astigmatism. It measures how much correction is needed.
- AXIS: The direction of astigmatism, measured in degrees.
- ADD: Found in multifocal prescriptions (like bifocals) — it’s the extra strength for reading.
- PD (Pupillary Distance): The distance between your pupils. This helps center your lenses for sharp vision.
