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.
吸收紫外光380nm到400nm范围内的化合物,但避免在蓝光范围内吸收,从而赋予黄色,即410-420nm具有适合制备光学
树脂或塑料的折射特性,例如,用于制造眼科透镜。还描述了制备这些化合物的方法,含有这些化合物的光学透镜以及制造这些化合物的方法。
