Step 1

Put on any pair of clear eyeglasses.
Face the camera directly.
Snap a picture.

(It helps to be close up to the camera,
and in a well-lit area.)

Step 2

Remove the glasses.
Read the size printed on the inside of the frame.

(It will look something like this: 45-21-145)

Step 3

Email the photo to
customer service
with the frame size information.
