Looking into your mirror,-
1 - hold a ruler so it is lined up with each temple.
2 - Measure in inches the distance between your left and right temples.
3 - Use the chart below to convert your measurement to a frame size that may suit your face:
Please note: The fit is more snug with wrap style frames
You could also use the size from a current frame you own. Look on the inside of each
temple to find the size of the frame (see illustration below). The eye size is usually
first, then the bridge size, then temple size.
Note: If the eye size is not on the temple, look under the bridge.
