frame fit calculator.

wide and square faces suit rounded boston and oval frames. round faces suit rectangular and squared frames. long faces suit deeper lenses. heart and inverted-triangle faces suit bottom-weighted rounds and aviators. diamond faces suit gentle upsweeps like cat-eyes. oval faces carry nearly every shape.

it depends on your face width, temple track (the width between the points above your ears), pupillary distance and bridge fit. a well-fitting frame is usually 4 to 20mm narrower than your temple track, because acetate arms open about 2 to 10mm per side.

yes. the camera tool uses your phone's front camera to read your pupillary distance, face width, temple track and bridge, works out your face shape and the frame shape that suits it, and suggests a frame colour from your skin tone, eye colour and hair colour. hold the phone at arm's length, level with your eyes, and look at the lens rather than at the screen.

yes. take a photo or upload one, line the crosshairs up with your pupils, and the recommended frame is drawn over your face at true scale. tap any frame to swap it onto your photo. the picture stays on your device and is never uploaded or stored.

pupillary distance is the distance between the centres of your pupils, in millimetres. measure it with the camera tool, a ruler in a mirror, or ask your optometrist. it is often printed on your prescription or lens order.

the first number is the lens (eye) width in millimetres, the square separates it from the bridge width, and a third number, when printed, is the temple arm length. for example 48□22 145 means a 48mm lens, a 22mm bridge and 145mm temples.

modern freeform progressive lenses fit comfortably from about 34mm of lens height. taller lenses give a longer corridor and easier adaptation.
