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.

Abstract: An integrally formed pair of lenses has a curved body and a curved bridge formed on the middle portion to divide the body into two lens portions. The bridge has a radius of curvature different from that of the lens portions so a nose pad can be formed without any additional processes being necessary. Accordingly, the appearance of a pair of glasses with the integrally formed pair of lenses is versatile, and the cost of manufacturing the glasses is reduced.
