Frame width is the horizontal diameter of the full frame width, and it’s the primary way we determine fit. (Note: You will not find this number on your glasses.). If your current glasses do not fit well, use them as a gauge towards a better fitting pair. Find a frame that is slightly wider than your face — no more than a finger width between the temple and your face. Origin offers 4 different frame sizes (XS, S, M, L) so choosing the right one is key to making sure your new glasses correctly fit your face.
| XS | 110 -122 mm |
| S | 123 - 128 mm |
| M | 129 - 134 mm |
| L | 135 - 150 mm |
For example if your glasses has the numbers 55 [] 18 - 145 (in millimeters), here are what they represent:
55 (mm) will represent the width of the lens. Usually a 2 digit number in the 40-62mm range. You have a leeway of 2-3mm on this measurement
18 (mm) will represent the width of the bridge. Usually a 2 digit number in the 14-24mm range. You have a leeway of 1-2mm on this measurement
145 (mm) will represent the overall length of the arm. Usually a 3 digit number in the 110-150mm range. You have a leeway of 2-3mm on this measurement
