How does glasses sizing work?

Most glasses and sunglasses come in a range of sizes and we often have customers ask what size they are. To complicate the matter glasses manufacturers print multiple measurements on their frames. These relate to the eye size (that's the measurement of the width of the lens), the length of the glasses arms, and the distance between the two lenses.

This means that unlike shoes or clothes, one glasses frame sized 50 might fit you but another sized 50 might not. This is because that 50 measurement only relates to one specific measurement of a part of the frame and not the frame as a whole.

Generally we say ignore the sizing. Find somewhere to try as many glasses designs as possible and take your time choosing something that looks and feels good.
