N2 - During the blinking process, the posterior surface of the eye lid interacts with the anterior surface of the cornea, which is a complex tribological system. In this paper, a simplified eye model is used to investigate the interaction between the above two surfaces during blink, using Finite Element Analysis (FEA).The analysis simulates the eye lid motion determined experimentally and available in the literature. The deformation and shear stresses on the ocular surface are recorded. Large deformations are observed during the movement of the eye lid at the point where the peripheral cornea forms the limbus. The large deformations due to the shear stresses is the result of high frictional forces generated due to poor quality of tear film between the interacting surfaces, resulting in dry eye condition. The FEA simulation enables a better understanding of the stresses and friction during the blinking process and therefore the dry eye condition.
