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.
