Frame size is usually defined by lens, bridge and temple width. These values are always displayed in that order, in millimeters. As a reference, you may want to check the size of your current eyewear, by looking at the inside temple. Should you see a fourth number at the end, this refers to lens height (i.e. 53/21/140)
