Eyewear lens creation using additive techniques with diffuse light

A method for creating a spectacle lens, the method comprising:

• receiving input information including a lens prescription and wearer information;
• calculating creation instructions based on the input information, the creation instructions including:
• 1) an irradiation pattern, 2) an exposure time to use a light transmission of the irradiation pattern to form a lens having the lens prescription and the wearer information, and 3) a resin composition;
• initiating the light transmission of the irradiation pattern from a light source through a diffuser into a container holding resin held within a substrate, wherein each point in a thickness of the resin sufficient to form the lens is illuminated by at least 10% of an area of the diffuser;
• and
• stopping the light transmission after the exposure time to form the spectacle lens, wherein the spectacle lens meets the creation instructions, wherein a single polymerization front has the shape of a target surface of the spectacle lens that meets the creation instructions, wherein the substrate includes embedded electronic circuits or embedded image formation systems.
