This is where we are normally stuck when purchasing online.
SODAMON products follow international standard called “BOXING SYSTEM”.
You may be able to see following example of [SIZE: 54ㅁ12 145] on product specification section.
This indication is imprinted on inner temple of all our products.
“54” means width of lens, “12” means distance between lenses (bridge), and “145” means length of temple (leg).
Also, for your better understanding, SODAMON provides extra information on FRONT WIDTH
(meaning total width of eyewear as if seen from right in front of it) and width*length size.
Size may be slightly different depends on how you see/measure.
It would be best to check your own sun/glasses for above information when considering/purchasing eyewear.
