Disclosed is a blue light absorbing compound, its preparation method and use. The compound has high stability and is suitable for high temperature processing conditions as well as outdoor application. A method of covalently bonding a blue light absorbing compound with an ultraviolet light absorbing compound for increasing its stability is also provided. The compound is capable of absorbing or blocking ultraviolet light (UVA, UVB) and blue light to protect eyes. But long-wavelength blue light can be absorbed diminishingly, so that the transmitted light has a particularly good visual experience.
揭示了一种蓝光吸收化合物,其制备方法和用途。该化合物具有高稳定性,适用于高温加工条件以及户外应用。还提供了一种通过共价键合蓝光吸收化合物和紫外线吸收化合物以增加其稳定性的方法。该化合物能够吸收或阻挡紫外线光(UVA,UVB)和蓝光以保护眼睛。但是长波长的蓝光可以被吸收得很少,使得透过的光具有特别好的视觉体验。
