Abstract: From the perspective of patent information, we can deeply understand the development status of photochromic spectacle lens, provide support and help for the research and development of related technologies in the future, and promote the further development of the glasses industry. In this paper, the trend of patent application, the distribution of countries and regions, the situation of main patent applicants and the classification of IPC of photochromic spectacle lens in the world are analyzed. The results show that the patent application of photochromic spectacle lens in the world has gone through three stages, and is now in a stable development period. The number of patent applications of photochromic spectacle lens in China is in the second tier of the world. During the research and development of photochromic spectacle lens, the hot technology field has undergone many changes, and the main patent applicants have their own advantages in different technical fields.

Key Words: Patent analysis; Photochromic; Spectacle lens; Resin lens

早期光致變色眼镜片属于玻璃材料,如今变色镜片已经向有机材料发展。当前光致变色眼镜片技术包含3种,即基变技术、膜变技术和埋入变色技术,均可达到光致变色功能效果。目前仅有黄锦胜[1]等个别学者,基于专利视角对光致变色眼镜片国内的专利情况进行了研究,为该领域的技术发展现状作出了有意义的探索。从全球专利信息的角度,最早是在1960年由National Cash Register公司提出了专利申请,申请号为AU241101。公开了一种透明光学观察装置,为光致变色技术在眼镜方面的应用提供新思路与新想法。随后在1961年,康宁公司提出了一篇题为Phototroper Glasgegenstand的专利申请,申请号为DE1421838。描述了一种玻璃制品的改进,首次制备出具有光致变色功能的玻璃眼镜片,5年后向市场推出了卤化银光致变色玻璃镜片。……
