Ray Ban Sizing:

When looking for the correct Ray Ban eyeglasses size, it is important that a person understand how eyeglasses and sunglasses are measured.
Typically, sunglasses will be a bit bigger than eyeglasses because the intention is to block sun from the whole range of vision.
In addition to the exact eyeglass frame sizes, the shape of the eyeglasses are also important as it relates to the shape of a person’s face.

The eye size is a measure of the distance, in millimeters, across one of the lenses (the first two digits of the size.)
The bridge size is the horizontal length, in millimeters, between the two closest points of the lenses as measures across the bridge of the frames (the second two digits of the size.)
An example would be 5020, with 50 being the eye size, 20 being the bridge size.
