Temple length can fall between 120mm and 150mm with 135mm, 140mm, 145mm and 150mm being the most common.
FRAME WIDTH
As a golden rule, your eyes should be nearly centered in the width of the lenses. A frame that is too wide will make your eyes look close together, while a frame that is too narrow will make your face look much bigger and wider.
LENS WIDTH
The maximum width of the lens size in the frame, measured from the bridge. The width is limited by the frame style so if you personally favor wider lenses, you will need to go for frames that wider lenses fit in.
LENS HEIGHTÂ
The maximum height of the lens size in the frame which is measured from the tip to the bottom of the lens aperture of the frame. This measurement is especially important for bifocal lenses or progressive lenses.
BRIDGE WIDTH
Bridge width is the gap above your nose between the lenses. It is the shortest distance between the lenses, typically ranges from 14mm to 24mm. If you have a narrow bridge or your eyes are a close set, you will want this number lower (15mm to 18mm) and if you have a wider bridge or a wide set eyes, you will like to have a higher number (18mm to 22mm).
