Abstract: Coating compositions yielding cured coatings that exhibit excellent abrasion-resistance and hardness for use on polymeric substrates such as the front side of optical lenses, in a manner that meets or exceeds the stringent requirements for such use. The compositions include a monomeric organofunctional silane, and colloidal silica present in an amount sufficient to improve abrasion resistance as compared to a composition lacking the colloidal silica.

Abstract: A coating composition based upon at least partially hydrolyzed epoxy-functional alkoxy silanes and having particular utility in forming tintable, abrasion resistant coatings on lenses. Incorporation in the composition of a non-hydrolyzed epoxy-functional alkoxy silane provides a desired reduction in viscosity. Incorporation in the composition of a polyether surfactant provides a cured coating of the composition with increased tintability.

Abstract: A lens coating system, which includes a gripper assembly for transferring and loading lenses, further includes one or more features to facilitate improved lens handling within the system. The one or more features includes a sensor assembly that is adapted to detect whether a single blocked lens or a pair of blocked lenses is being loaded by the gripper assembly into a spindle assembly of the system, and/or a sensor assembly that is adapted to detect a displacement of a lens holding element, from which lenses are transferred, by the gripper assembly, when impinged upon by the gripper assembly.

Abstract: A shaft assembly of a lens coating system includes a first portion reversibly engagable with a second portion. A reciprocating drive disengages and subsequently re-engages the shaft first and second portions. A lens holder is coupled to an arm, which is coupled to the shaft first portion. Another drive, coupled to the shaft second portion, rotates the arm about an axis of the shaft assembly, when the first and second portions are engaged, such that the lens holder travels along a pathway surrounding the assembly. The system includes a plurality of stations, each station having an opening along the pathway, so that the rotating drive may transfer the lens holder into proximity with each station, when the shaft first and second portions are engaged, and the reciprocating drive may transfer a lens, held by the lens holder, into and out from each station through the opening thereof.
