Common Questions
Frame Fit, Answered
What do the numbers in a fit code like 52-21-150 mean?
It's eye size – nose bridge – temple length, all in millimeters. Eye size is the width of one lens, the bridge is the gap over your nose, and temple length is the arm from hinge to ear. Every Peepers product page lists the frame's fit code and full measurements.
Where do I find a frame's measurements?
Every product page lists exact measurements — eye size, nose bridge, temple length, and overall frame width — plus the fit code. The easiest starting point is a pair you already own: most glasses have their fit code printed inside the temple arm, so you can compare directly.
How do I know if a frame runs narrow, average, or wide?
Peepers labels each frame's fit — narrow, average, or wide — based on its overall frame width, and you can filter styles by fit on this page. If a frame you own fits well, match its frame width within a few millimeters.
Can I see frames on my face before buying?
Yes — use Virtual Try-On to see any style on your own face. And every order is covered by a 90-day return and exchange policy, so if the fit isn't right you can swap the style, color, or strength.
