Abstract:
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 main absorbance area having an absorbance peak portion. The main absorbance area has a first wavelength range between 420 nm and 440 nm formed as a high-energy blue UV absorbance area.
