摘要： A blue light blocking system including a pyrazoline compound of formula (I) or/and a phenylacrylic compound of formula (II) is provided. The compound of formula (I) or formula (II) can absorb most blue light of shorter wavelength that hurt eyes, but let that of the longer wavelength pass through, so that the transmitted light makes an excellent visual effect for human. The system can be applied to products such as optical films, optical lenses, goggles, skin care, lighting, coatings, adhesives, or panels. These products have a light-colored appearance and their transmitted light makes for an excellent visual effect.

摘要： 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.
