Finding your size:

If you already own a pair of glasses, you’ll find numbers engraved on the inside of the eyewear temple.

These numbers indicate the following:

LensWidth51

BridgeWidth18

TempleLength140

LENSHEIGHT36

The first number is the lens width followed by the bridge width. The third number that represents the temple length, or the measurement of the 'arms' of your frame.

In some cases there may be a fourth number that indicates the lens height.
