Most frames come in several colors. Pick yours on the frame page.
How it works
Browse men's, women's, kids' and safety frames. Pick a color and a size. The size is printed inside the temple arm of glasses you already own.
Type in your single vision Rx and PD, or upload a photo or PDF of your prescription. You can do both.
Check out with your PayPal account or a debit or credit card through PayPal. We email you when your glasses ship.
Single vision only
Single vision lenses have one power across the whole lens, for distance or for reading. We use SPH, CYL and AXIS for each eye, plus your PD. If your prescription lists an ADD for bifocals or progressives, we can't fill it yet.
Example prescription
| Eye | SPH | CYL | AXIS | ADD |
|---|---|---|---|---|
| OD (right) | -2.25 | -0.75 | 180 | — |
| OS (left) | -2.00 | -0.50 | 175 | — |
PD 63 · Single vision: no ADD, no prism.
