A lens forming apparatus for preparing a plastic eyeglass lens includes a first lens curing unit (810), a second lens curing unit (820) and a conveyor system (850) for moving mold assemblies between the two units. The apparatus may also include an anneal unit (830) configured to apply heat to a substantially polymerized lens. The apparatus may be used to form an eyeglas s lens from a lens forming composition that 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. |
