  • Patent number: 8545010
    Abstract: The present invention relates to dual-lens eyeglasses including an eyeglass frame and two lens units permanently installed on the eyeglass frame. Each lens unit includes two lenses arranged in optical alignment with each other. The lenses can be optical lenses or sunglass lenses. The optical lenses can be selected from known lenses such as corrective lenses, myopic corrective lenses, reading glasses lenses, progressive lenses, etc. The sunglass lenses can be selected from polarized lenses, tinted lenses, or photochromic lenses. Without the use of sub-frames, two lens units are permanently installed on eyewires of the eyeglass frames, enhancing the integration effect of the eyeglass frames. In addition, each lens is directly fixed and installed on the eyeglass frames, so that the installation is reliable and the lenses will not fall off easily. Furthermore, the lenses can be easily installed on full-rim, half-rim or rimless eyeglass frame.
