Does my prescription fit?
Pick your glasses and enter the numbers from your prescription (use the stronger eye). You'll see a verdict and the best-priced lab in seconds. Everything runs in your browser; nothing is sent anywhere.
1 Your glasses
2 Your prescription (stronger eye)
Where to find your numbers
- Look at your glasses prescription (or ask your optician to email it).
- SPH is your main number, e.g. −2.50. CYL is for astigmatism; leave it at 0 if there isn't one.
- Use the eye with the bigger number. Ignore AXIS and ADD here.
Check every model at once

How the check works
- We convert your prescription to minus-cylinder form and check both principal meridians (SPH and SPH+CYL) against the published limits. That's slightly conservative.
- "Total power" ranges (Meta) mean sphere and cylinder combined. Where a brand only states a sphere range, we check sphere and cylinder separately and say when a cylinder limit isn't published.
- Most labs don't publish a maximum prescription. We mark a lab likely only when it publishes support for the lens type you need and either your power is inside the frame's official range or inside a limit the lab publishes. Otherwise it says ask the lab.
- Prism: Tajima Direct states that Meta's own prescription service doesn't offer prism; we use that for Meta-brand frames.
- Data last checked 2026-10-17. Not medical advice; your optician has the final say.
