ABSTRACT:
A color contrast enhancing lens made from adhering two different lenses and a membrane together. It includes a color enhancing lens whose specific component will selectively absorb the yellow light in the visible spectrum, which enhances the user vision by enhancing the distinction between red and green. It also includes an ultraviolet blocking lens whose special compounds will absorb the majority of violet light and a part of blue light. It also includes a light polarization membrane whose special structure can reduce strong light. It can also absorb the majority of violet light and keep a low transmission rate of blue light, thus reduced the retina injury caused by overexposure to blue light. It can also block the invisible ultraviolet and reduce strong light. So while the users' eyes are protected, they can also enjoy their view.
