In this paper, dynamic responses of contact lenses are investigated. Dynamic restoring force of contact lenses were measured using Levitation Mass Method (LMM) proposed by Fujii. This sophisticated experimental system has a block, which can smoothly travel along a guide due to a pneumatic linear bearing. Thus, the block is levitated by air film at the interfaces between the block and the guide. By this system, the block can move toward z direction under low friction. Therefore, we carry out numerical analysis of dynamic responses for the lenses under same conditions with the experiment. Contact lens is modeled using elements for nonlinear complex restoring force. This nonlinear complex element is connected to the levitated block, which is modeled by three-dimensional finite elements. Like the experiment, initial velocities are given to and hysteresis curves are computed. Nonlinear complex spring constants are identified by the obtained curves. We also calculate the time histories of displacement, velocity, and acceleration by the analysis.
