An analysis is made of the motion of a contact lens normal to the eye through a tear film. The eye is modeled as a rigid sphere and the lens as a deformable spherical cap. Graphs of pressure distribution and tear film thickness variations are obtained. It is found that the pressures are very markedly reduced and film thicknesses increased by decreasing the modulus of the lens materials.
