5 1/2 on left temple, the right temple as you can see was attempted to be repaired years ago - the temple itself is fine, it is the attachment for the hinge on the specs that needs repair.. the hinges are fine as well - these are already with a prescription so you will want them replaced with you own) the black heavy plastic is in decent condition and will shine up well - THESE ARE FOR A REPAIR but they are a repair that can be made with some time and energy
