US Patent 11698541 Optical lens device with chroma enhancement

An optical lens device includes a lens body, an optical filter and an optical absorbance portion. The lens body has a first lens surface and a second lens surface between which to form the optical filter where is to provide the optical absorbance portion. The optical absorbance portion includes a first main absorbance area having a first absorbance peak portion and a second main absorbance area having a second absorbance peak portion. The first main absorbance area has a first wavelength range between 420 nm and 440 nm formed as a high-energy blue UV absorbance area while the second main absorbance area has a second wavelength range between 580 nm and 610 nm.
