The size to choose is directly linked to the lens diameter

Choosing the right size

If you have an old pair of glasses that look good, you can easily use the measurement information stamped on them. Usually the information
you need is on one of the arms or inside the bridge.

The measurements need not be exact, but the closer they are to those of your old glasses, the more the new ones will look similar on your face.
  1. Diagonal of the lense : Distance between the upper corner of one side to the lower corner of the opposite side.
  2. Bridge Width (ex : 18) : To determine the correct size of your Ray-Ban sunglasses, you need the width of the bridge,
    which determines how the glasses rest on your nose.
  3. Height of the lense : The height of the lense will show you exactly where the lense will end on your face.
  4. Lens Diameter (ex : 54) : The diameter of the lens is an option of choice and is an indication of how the glasses will appear on your face.
  5. Temple (ex : 135) : The length of the temple is the length of the frame's arms from the front of the frame to the temple which secure the frame behind the ears.
On your current glasses
The front measurement includes the DIAMETER OF THE LENS (F) and the WIDTH OF THE BRIDGE (G) measured in millimeters and usually
separated by a small dash or rectangle (e.g.: 50 - 22). The lens diameter is the width of the lens, measured from the bridge, and the width of
the bridge is the distance between the lenses above the nose, as shown in the figure below. Sometimes, the vertical measurement of the lens
and the length of the arms are also present.
