Compounds that absorb ultraviolet light 380 nm to 400 nm range but avoid absorption in the blue light range, thereby imparting yellowness, i.e., 410-420 nm have suitable refractive characteristics useful in the preparation of optical resins or plastics suitable, for example, for the manufacture of ophthalmic lenses. Methods for making the compounds, optic lenses containing the compounds, and methods for making these are also described.
吸收380纳米到400纳米紫外线但避免吸收蓝光范围的化合物,因此赋予黄色,即410-420纳米具有适合制备光学树脂或塑料的折射特性,例如用于制造眼科镜片。还描述了制备这些化合物的方法,含有这些化合物的光学镜片以及制备这些的方法。
