How to pick right frame size
The size numbers next to the frames are measurements in mm (millimeters).
There are three figures listed on the side of the frame,
* the first number is the width of the lenses;
* the second is the bridge distance, or distance between the lenses,
* the third is the full length of the temple/arm (including the part that goes behind your ear)..
There are also 2 numbers not shown on the frame, TOTAL WIDTH and LENS HEIGHT
To ensure the frame size is right for you, the most important figure is TOTAL WIDTH.
To find out your TOTAL WIDTH, you can either measure the hinge to hinge distance of your own frame, or you can measure the distance between the front edges of your forehead.
