Abstract: An apparatus for preparing a plastic eyeglass lens includes a coating unit and a lens curing unit. The apparatus is preferably configured to allow the operation of both the coating unit and the lens curing unit. The apparatus may also include a post-cure unit and a controller. The controller is configured to control the operation of the coating unit, the lens curing unit and the post-cure unit. A lens forming composition may include an aromatic containing polyether polyethylenic functional monomer, a photoinitiator, and a coinitiator. The lens forming composition may be cured by the application of activating light or activating light and heat.

Abstract: A high volume lens curing system is described. The high volume lens curing system may be configured to cure multiple eyeglass lenses in a continuous manner. An embodiment of the lens curing system includes an apparatus for preparing an eyeglass lens. The apparatus may include one or more lens curing units and a mold assembly. At least one lens curing unit may include a heating system. In some embodiments, the apparatus may include a conveyor system configured to convey the mold assembly to, from or through the apparatus. The conveyor system may include a gating device configured to inhibit movement the mold assembly. In some embodiments, the apparatus may include an annealing unit, an air distributor and filters.

Abstract: Apparatus for making a plastic lens is described. More particularly, an apparatus for applying alternating periods of ultraviolet light to a lens forming composition is described. The lens forming composition is cured while the rate of heat generation and/or dissipation is controlled via manipulation of the duration of the ultraviolet light or the cooling in the curing chamber. The ultraviolet light is preferably directed toward the lens forming composition which is disposed in a mold cavity formed by two mold members. The ultraviolet light may be directed in pulses or continuously.
