What Do the Numbers on Glasses Frames Mean?

[Happy Hopping]

You may notice numbers such as “47-19-140” in the temple of glasses frames. But did you know these numbers actually describe the frame size? Glasses manufacturers typically use the same format to detail sizes. And it’s easy to find the correct frame size for your face type. Simply measure your face or check your current glasses to find the ideal size. Opticians and optometrists also rely on these numbers to determine the best fit. 
We’ve put together this guide to help you understand exactly what these numbers mean and how to read them correctly.  

Reading Frame Size and Dimensions
Before we review what these numbers mean, let’s first understand how to read frame measurements. You read the numbers from left to the right in the following order:

56/63 is the width of the lens, the 20/21 is the gap between the lenses

the reason they are different is because you have a flak jacket regular and a Flak Jacket AF (Asian-Fit)

if you look at them from the top the arch should be sharper on the regular the af should be flatter

like looking at more of a V and U.

I have 2 identical Oakley, except the pair of no. on the side

1 pair states: 03-915 63 O 20
2nd pair states: 03-915 56 O 21

I'm guessing 03-915 is the model no., but what does 63 O 20 means? and vs. 56 O 21?

That's the sizing.

thanks for the reply. When you said "gap between the lenses", you mean how thick the lens is?

And what's the suggest retail price of these 2 pair?

I got 3 pair of Oakley for free, w/ the 3rd pair being model 12-896, so I'm thinking of keeping 2 pair, and sell the 3rd pair.
