Photoelasticity is applied to measure the strain of the lenses of glasses. The lenses are fixed to two kinds of glasses frame, the old frames and the new ones whose rim lock mechanism is improved to reduce the strain of the lenses. The measurement results show that the strain of the lenses fixed with the new rim lock mechanism decreases by about 33% on the average of whole area of the lenses, compared with the old mechanism. At the center of the lenses, however, the strain of the lens fixed with new rim lock mechanism is roughly the same as that of the lenses fixed with the old rim lock mechanism.
