Frame size
Every frame carries three numbers inside a temple, in millimetres: lens width, bridge and temple length.
| Lens width (mm) |
Bridge (mm) |
Temple length (mm) |
| 50 |
20 |
145 |
Example: 50□20-145. Compare with a frame that fits you well; a difference of 1-2 mm in lens width is hardly noticeable.
