Patent number: 12645099Abstract: A double-sided composite spectacle lens and an inject mold therefor are provided. One surface of the spectacle lens is an aspherical surface, and the other surface is a designed aspherical surface used to inhibit astigmatism, and a spectacle lens formed by combining the two surfaces has two areas with different functions: optimizing optical performance, and thinning for aesthetics. By controlling the reduction of diopter and optimizing astigmatism on one surface, and inversely offsetting astigmatism on the other surface, the degree of astigmatism of the spectacle lens formed by combining the two surfaces is significantly lower than a diopter variation, and the degree of oblique astigmatism is significantly reduced. The aesthetic thinning effects of reducing the edge or center thickness of the double-sided composite spectacle lens are significantly enhanced by accelerating reduction of the diopter on one surface and changing from reducing to increasing the diopter on the other surface.Type: GrantFiled: January 3, 2024Date of Patent: June 2, 2026Assignee: SUZHOU MASON OPTICAL CO., LTD.Inventors: Haomo Yu, Xiaoyi Chen, Tao Feng, De Li
