2. You can easily find a set of 3 numbers on the inner side of one of the temple arms, which could help you find the right frames. All our frames have these numbers which are underneath the frames. They do not have to be exactly the same, a 1-3 mm tolerance is acceptable.
3. If you do not find these numbers, please measure the wearable width of your current pair or your best fit pair. The wearable width is the distance between the two temple arms when they are fully opened.
