Abstract:
1. A method of centrifugally casting a lens, comprising: providing a first rotatable tube having a first end and a second end connected by a longitudinal outside surface that defines an interior longitudinal cavity configured to receive at least one contact lens mold; introducing at least one mold into the internal longitudinal cavity of the first rotatable tube, the at least one mold containing a polymerizable liquid; at least partially curing the polymerizable liquid in the first rotatable tube via actinic radiation while rotating the tube; wherein the first rotatable tube includes at least one portion defining at least one aperture, wherein the at least one aperture extends from the interior longitudinal cavity to the longitudinal outside surface of the first rotatable tube, and the at least one aperture is configured to permit the transmission of actinic radiation into the interior longitudinal cavity during rotation of the tube, said at least one portion being at least partially made of material that is opaque to actinic radiation.
