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.

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

This invention provides a contact lens comprising a front surface, a back surface, and an identifying mark, wherein said identifying mark comprises one or more holes depressed into at least one of said surfaces of said lens.

Contact lenses bearing marks

This invention provides a contact lens comprising a front surface, a back surface and an identifying mark on at least one of said front surface and said back surface, wherein said identifying mark comprises a depressed region having a cross-section which comprises at least two intersecting concave surfaces at the bottom of said depressed region.

Contact lenses bearing identifying marks

A method and apparatus for the manufacture of optical polymer contact lenses in a closed mold, where a mold cavity is created between a front curve insert and a back curve insert, the side walls of the mold cavity being formed by the inner wall of a movable annular gate collar, the collar being positioned in a retracted position during polymer dosing and then moved prior to polymer cure into an extended position to complete the mold cavity and to separate the polymer curing inside the mold cavity from any waste polymer outside of the mold cavity.
