Mold for forming a contact lens and method of preventing formation of small strands of contact lens material during contact lens manufacture

This invention relates to a mold used for forming a contact lens and for a method of preventing the formation of small strands of contact lens material from the overflow of the contact lens mold during contact lens manufacture. This invention provides a mold for forming a contact lens including 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.
