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. ## Claims ### Claim 1 Eyewear comprising: a lens with optical power, the lens comprising: a non-laminate wafer, wherein the non-laminate wafer comprises a non-laminate chroma enhancement wafer having a thickness less than 1.1 mm, and wherein the non-laminate chroma enhancement wafer comprises one or more chroma enhancement dyes disposed in a synthetic resinous material, and wherein the non-laminate chroma enhancement wafer is configured to increase an average chroma value of uniform intensity light stimuli having a bandwidth of 30 nm transmitted through the non-laminate chroma enhancement wafer within a spectral range of 440 nm to 510 nm as compared to a neutral filter that uniformly attenuates the same average percentage of light as the non-laminate chroma enhancement wafer within the spectral range of 440 nm to 510 nm;
