Methods and systems for making an optical functional film

A method of manufacturing an eyeglass lens using a solution casting, lamination, or injection molding process, the method comprising:

• providing a first soluble polymer solution;
• providing a first dye solution comprising at least one dye having a property of attenuating one of 400 nm-455 nm violet-blue light, 570 nm-595 nm green-yellow light, or 760 nm-2000 nm infrared (IR) light;
• adding the first dye solution to the first soluble polymer solution to form a first dyed solution;
• casting the first dyed solution to form a first film;
• providing a second soluble polymer solution;
• providing a second dye solution comprising at least one dye having a property of attenuating one of 400 nm-455 nm violet-blue light with at least 30% absorption, 570 nm-595 nm green-yellow light with at least 20% absorption, or 760 nm-2000 nm infrared (IR) light with at least 20% absorption;
• adding the second dye solution to the second soluble polymer solution to form a second dyed solution;
• one of combining or fusing the second dyed solution onto the first film to form an at least two-layer film by one of the methods of i) surface coating, ii) dip coating, iii) spin coating, iv) slot die coating, v) scraper coating, vi) gravure coating, vii) spray coating, viii) roll coating, ix) brush coating, x) silk screening, xi) printing, xii) pad printing, or xiii) adhesive glueing;
• optionally, adding a third layer comprising a same or different solution material as the second dye solution with or without a dye as the first film or second film to form the at least two-layer film to form an at least three-layer film;
• optionally, bending the eyeglass lens to create a curved eyeglass lens;
• and
• one of:
• laminating or casting the at least two-layer film to make the eyeglass lens with a same or different sheet material, wherein the eyeglass lens comprises a thickness of between 0.02 mm-3.0 mm;
• or
• gasket casting the at least two-layer film to the eyeglass lens, wherein the eyeglass lens comprises a thickness of between 0.7 mm-10 mm;
• or
• co-injection molding the at least two-layer film to the eyeglass lens, wherein the eyeglass lens comprises a thickness of between 1.0 mm-10 mm.
