Abstract

The invention relates to an anti-blue-light resin monomer and an anti-blue-light resin material obtained by polymerizing the anti-blue-light resin monomer, wherein the monomer comprises a quinophthalone compound represented by a formula A, core-shell structure nanometer titanium dioxide, an ultraviolet ray absorber and an optical resin monomer according to a weight ratio of (0.1-0.2):(0.5-3.0):(0.2-2.0):(100-150). The preparation method comprises: adding the solution of the quinophthalone compound (represented by the formula A), the core-shell structure nanometer titanium dioxide and the ultraviolet ray absorber to the macromolecule monomer for preparing the optical resin. According to the present invention, the anti-blue-light resin monomer and the anti-blue-light resin material can distinguish and absorb blue lights at different wavelength bands, such that the harmful blue light at the medium-short wavelength bands maintains the low transmittance, and the blue light at the long wavelength bands and other wavelength bands maintains the high transmittance so as to easily protect the eyesight and well solve the problem of the damage of ultraviolet light and blue light on human eye.The formula A is defined in the specification.

Description

technical field [0001] The invention belongs to the technical field of light-absorbing materials, and in particular relates to a light-absorbing material with specific absorption wavelength in the 220-470nm spectral region, a precursor and a preparation method thereof. Background technique [0002] We all know that ultraviolet rays can damage people's eyes, but many people don't know that blue light in visible light can also cause damage to eyes. As part of visible light, blue light has extremely high energy, and its wavelength range is between 400 and 500nm. With the widespread popularization of electronic products such as computers, mobile phones, and ipads, unnatural light with blue light as the main body will cause irreversible damage to human eyes. Damage, causing dry eyes, fatigue, tearing, accelerated myopia, macular area disease and other problems. According to the orange warning issued by the World Health Organization (WHO) at the end of 2009: the potential invisib...
