Abstract: There is disclosed a fixture or apparatus for use in the tinting of a contact lens or the like. The fixture includes a tube having a body portion and a closed end portion, which includes an annular masking structure to support the lens and define a ring-like unmasked area. Proximate the masking structure, a tinting medium receiving chamber is defined. A method for using the fixture is also disclosed. In an upright position, the tube body portion is filled with a preparatory solution. Into this fluid-filled tube, a contact lens is dropped. As the dropped lens passes through the liquid column, the hydraulic forces acting thereon produce a state of dynamic equilibrium, with the lens convex side down. This action tends to properly position and center the lens as it comes to rest upon the mask structure. Next, a mandrel device is inserted into the tube to fix the lens in place against the mask.
