Frame Fit

Eyewear is measured in millimeters. To get the overall frame size, add the eye size to the bridge size. These measurements are usually found on the inside of the frame.
The first number is the eye size which is measure from the outermost edges of the lenses.
The second number is the bridge size which is the distance between the lenses.
The temple length is not recorded on the frame but can be measured from the tip.
