Provided in the present invention are a novel blue light-absorbing compound, the synthesis thereof and an application thereof. The compound of the present invention has high stability and is suitable for high temperature processing conditions as well as environments exposed to the outdoors. In addition, the present invention also sets forth a novel method for covalently bonding a blue light-absorbing compound to an ultraviolet light-absorbing compound so as to increase stability. The compound of the present invention is capable of absorbing ultraviolet light (UVA, UVB) and short-wavelength blue light so as to protect the eyes. Long-wavelength blue light may also be decreasingly absorbed so that transmitted light provides a particularly good visual experience. The present invention may be applied to products such as optical films, plate optical lenses, goggles, skin care products, lighting products, paint, adhesives, panels, and so on. |
