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. The lens forming unit may include an LCD filter disposed between activating light sources and a mold assembly. The mold assembly preferably includes two mold members held together by a gasket. The gasket preferably includes four protrusions spaced at 90 degree intervals about the gasket. A lens forming composition may include a first photochromic compound, a second photochromic compound and a light effector. The light effector may alter the color of a lens when exposed to photochromic activating light, when compared to a lens formed from a lens forming composition which does not include a light effector.

1. A system for preparing an eyeglass lens, comprising:an apparatus, comprising: a first mold member having a casting face and a non-casting face; a second mold member having a casting face and a non-casting face, the second mold member being adapted to be spaced apart from the first mold member such that the casting faces of the first mold member and the second mold member at least partially define a mold cavity; a coating unit configured to produce a coating on at least one of the mold members or the eyeglass lens; a lens curing unit configured to cure at least a portion of a lens forming composition into the eyeglass lens by directing activating light toward mold members; a post-cure unit configured to apply heat and activating light to the eyeglass lens to substantially complete curing of the eyeglass lens; a programmable controller configured to substantially simultaneously control operation of the coating unit, the lens curing unit, and the post-cure unit; and a lens forming composition adapted to be disposed within the mold cavity, comprising: a monomer that cures by exposure to activating light to form the eyeglass lens; and a photoinitiator that initiates curing of the monomer in response to being exposed to activating light.
