Abstract
Description
【発明の詳細な説明】 〔産業上の利用分野1 本発明は、眼鏡レンズに用いる素材に関する。[Detailed description of the invention] [Industrial application field 1 The present invention relates to materials used for spectacle lenses.
[従来の技術]
従来の眼鏡レンズは、その素材としてクラウンガラスや
プラスチックを用いていた。[Prior Art] Conventional eyeglass lenses have used crown glass or plastic as their materials.
〔発明が解決しようとする課題]
しかしながら、前述の従来技術は、手に入いつやす(普
及している素材であることから高価値感の薄い製品であ
る。また、素材の屈折率も低い。[Problems to be Solved by the Invention] However, the above-mentioned conventional technology is a product that does not have a high value because it is a material that is available and popular.In addition, the refractive index of the material is low.
よって、本発明は、この問題を解決するもので、その目
的とするところは、高価な素材を用いた高級製品、また
、素材の持つ高屈折率とほとんどキズのつかない表面の
硬さによる高付加価値製品を提供することろにある。Therefore, the present invention aims to solve this problem, and its purpose is to create high-quality products using expensive materials, as well as high-quality products that utilize the high refractive index of the material and the hardness of the surface that hardly scratches. Our goal is to provide value-added products.
〔課題を解決するための手段]
本発明の眼鏡レンズは、人造サファイヤガラスを素材と

等が含まれる。The material used for the eyeglass lens of the present invention is artificial sapphire glass manufactured by a molding method such as the Bernoulli method or the salvage method, and the front curve (RL) and the back surface are formed by polishing and other processing in the same way as with conventional eyeglass lenses. Eyeglass lenses for vision correction that provide power through a combination of curves (R2), etc., with an outer diameter of 60
mm or more, and the minimum center thickness of lenses for myopia is 1 mm or less,
Thin, fashionable eyeglass lenses that utilize the high refractive index of artificial sapphire glass (Figure 1), and others.
Spectacle lenses include lenses for sunglasses, lenses for ready-made reading glasses, lenses for vision correction, etc. Lenses for vision correction include lenses for nearsightedness, lenses for farsightedness, lenses for astigmatism, lenses for presbyopia, bifocal lenses, and Includes a mix of the above lenses (for example, lenses for near astigmatism, etc.), aspherical lenses, etc.
