The present disclosure includes systems, devices, and methods for preventing contamination during formation of an optical article. In some implementations, a device for preventing contamination of a mold cavity during injection molding of a function wafer includes a containment band having an annular base that defines a first opening configured to receive a functional wafer. The device also includes one or more sidewalls that project a first direction from and surround at least a portion of the first opening. The one or more sidewalls may be configured such that, during formation of an optical article, a first portion of the functional wafer is in contact with the one or more sidewalls.

The invention provides a system for coating an optical article with a coating composition (), comprising a chamber configured to receive said article, a coating device configured to carry out a coating treatment of said composition for depositing it on said article in said chamber, by vaporizing said composition and by exposing at least a face of said article to the vaporized composition, and a control unit configured to control said coating device for coating said article by vaporizing said composition; said coating device being formed as a single cartridge unit comprising a casing () configured to contain said composition, a vaporizing conduit () opening both into said casing and outside of said coating device, and a propelling member () configured to pressurize said composition; said coating device being configured to put in fluidic communication said propelling member in an operative state with said casing in order to carry out said coating treatment for coating an article.

System for coating an optical article with a predetermined coating composition, coating device for such a system and method for using the system

A method for laminating a film on to an optical article and a bi-layer adhesive for use in the method. The bi-layer adhesive includes a latex adhesive layer and an HMA layer sequentially disposed on the film and dried to form a solid layer of uniform thinness throughout to provide optical quality. Various types of films may be employed to provide an optical function. Following optional pre-treatment steps, the adhesives are coated on to the film. An optical hot press technique is used to deliver heat and pressure over a short period of time to form a functionally-enhanced optical article with high adhesive strength.
