How we name sizes
Size is based on the lens span: two lenses plus the bridge. It is the same scale as the Size filter in our shop.
Compare with your glasses
Most glasses have three numbers printed on the inside of the temple arm. If you own a pair that fits well, compare its numbers with the ones above.
What the numbers mean
Lens widthThe width of one lens. The first number on the temple arm.
BridgeThe space between the two lenses, over your nose. The second number.
Temple lengthThe full length of the arm, from the hinge to the tip. The last number.
