ABSTRACT:
A segment measuring gauge for ophthalic frames. A base member has a lower edge and an upper portion and a plurality of fingers extending vertically from the upper portion. A scale is formed on the gauge extending from adjacent the base member lower edge toward the vertically extending fingers. In use, the gauge is inserted into eye glass lens rim openings with the lower edge resting in the bottom portion of the lens well and the fingers interleaving the upper rim portion enabling the proper segment height to be read as well as to determine if the patient has a hyper-condition.
