ABSTRACT:
This invention provides a mold for forming a contact lens comprising an overflow collector, which causes the overflow reactive mixture to be accumulated, and not to spread out as it would upon the typically flat surface of a prior art mold. This invention further provides a method of preventing the formation of contaminating pieces of overflow reactive mixture comprising the step of: preventing the overflow reactive mixture from spreading out on the mold.
