Hi Jessie, thanks for your inquiry. Choosing a perfect frame size online can be tough sometimes, here's what we can do for you: First, kindly check how to measure eyeglasses size
and find the perfect size
. You can also check the numbers on your old glasses that look like 51-18-135. The 1st is the width of one lens; the 2nd is the bridge distance, and the 3rd is the length of the temple piece that goes behind your ear. Please feel free to contact us if you need further assistance on this matter, you may also call our toll-free hotline at 1-855-487-6006 opens every day from 5am - 8pm PST.
