Frame Width

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
