Abstract
Certain embodiments disclosed herein include lenses for eyewear with a molded wafer and a molded clear resin lens component integrated onto a surface of the molded wafer. The molded wafer can include an optical filter that enhances one or more properties of filtered light. The optical filter can be, for example, a contrast-enhancing, color-enhancing, and/or chroma-enhancing filter. The clear resin lens component can be shaped such that the lenses have optical power. In some embodiments, the molded wafer is integrated onto a surface of a polarizing wafer.
Claims20
Eyewear comprising:
- a lens comprising:
- a base layer having a front surface and a rear surface;
- and
- an optical element disposed on the front surface of the base layer, the optical element comprising:
- a first layer comprising a first polymeric material;
- a second layer comprising a second polymeric material;
- and
- a functional layer between the first and the second layers,
- wherein the first or the second layer at least partially comprises an optical filter comprising one or more chroma enhancement dyes, the optical filter configured to increase an average chroma value of a uniform intensity light stimuli having a bandwidth of 30 nm within a visible spectral range transmitted through the optical element compared to a neutral filter that uniformly attenuates an equal average percentage of light as the optical filter within the visible spectral range.

A method of manufacturing a lens, the method comprising:
- forming a functional wafer comprising a functional layer disposed between a first polymeric layer and a second polymeric layer, the first or the second polymeric layer comprising an optical filter;
- placing the functional wafer into a cavity of a mold;
- and
- forming a lens base by integrating a lens material onto a surface of the functional wafer while the functional wafer is within the cavity of the mold.
