Spectacle frames can be classified into two types, namely full-rim and rimless types, on the basis of the method they use for retaining the lenses. In this study, we measured the displacement distribution of these two marketed spectacle frame types by estimating the opening load exerted on the temples of the spectacles when they are worn. In this experiment, we employed light sectioning, which involves scanning an object using a laser beam. The displacement distribution was measuring the spectacles' profiles before and after application of a load. The temple exhibited two-step displacement distribution in which the displacement gradient was large at a distance of approximately 40 to 50 mm from the end piece. We also conducted FEM analysis to investigate the influence of the rims on the mechanical characteristics of the spectacles. We found that the rimless spectacles should fit well and produce no discomfort since their temples are well displaced resulting in little pressure being applied to the head. Because the screw section is under great stress in rimless spectacles, however, they have a much greater risk of lens damage than full-rim spectacles.
