When purchasing eyewear online, we at OnlineGlassesShop recommend that you know which size frames fit you best. Therefore we advise you to look at the measurements marked on the side of your current glasses frames – for example, 50-17-145.
The first 2 numbers indicate the LENS WIDTH in millimetres (for example 50).
The next 2 numbers, (for example 17), indicates the BRIDGE WIDTH.
The last 3 numbers, (for example 145), indicates the TEMPLE LENGTH.
