Abstract
The motion of a gas permeable contact lens during blinking is analyzed. The contact lens is considered to be a planar, circular, porous disk. On one side, it is in solid contact with the eyelids, while on the other, the lens is separated from the corneal surface by a thin tear film. The rigid body dynamics of the lens are coupled with the fluid dynamics of the tear film, and a velocity slip condition is imposed at their interface. The coupled system of ordinary and partial differential equations is solved by a combination of analytical and numerical techniques subject to boundary conditions and physical constraints limiting the duration and extent of the motion of the lens.
