What are your glasses frame measurements?

Temple Length: The arms should fit comfortably along the sides of the head and reach just behind the ear. The tips of the arms should curve close to the back of the ear for a snug fit.
Bridge Width or "DBL": Bridge width is the distance between your two lenses (DBL), measured from the innermost point on each lens. The bridge, which rests across the top of the nose, should sit securely without pinching or falling down.
Frame Width: The frame width is the face of the frame and measures the width of your face. If it's too large, the temple arms will also be too long and cause the frames to slip or fall off.
Lens Width / Eye Size: The length of the lens from left to right; for best fit your eye should be nearly centered in the frame.
