Abstract
A key factor in determining the comfort level of eyeglasses is the clamping force at the temple. However, how to accurately measure and estimate the clamping force remains under-explored. Hence, to address this gap, we proposed a novel temple clamping force measurement method with a digital tension meter and developed a mathematical model to calculate the clamping force of the temples based on eyeglasses parameters (including length, one-side displacement, and flexural rigidity of the temples). To validate our method, we collected the simulated and physical datasets of different eyeglasses and conducted a multiple regression analysis to calculate the model parameters. The experimental results demonstrated the accuracy and reliability of the proposed method. This model can guide us in customizing the parameters of the eyeglasses to produce comfortable clamping forces for the users. Our codes and data will be publicly available at: https://github.com/Easy-Shu/Eyeglasses_Force_Modelling. Keywords: measuring temple clamping force, modeling temple clamping force, eyeglasses design, finite element analysis
