Document Type and Number:
WIPO Patent Application WO/2019/029148
Kind Code:
A1
Abstract:
An anti-blue light system containing a pyrazoline or/and cinnamic acid compound, an anti-blue light agent thereof having a structure of pyrazoline as represented by formula (I) or/and a structure of a cinnamic acid compound as represented by formula (II). The compounds as represented by formula (I) or/and as represented by formula (II) may fully absorb short-wavelength blue light so as to protect the eyes, and may also selectively absorb long-wavelength blue light. The anti-blue light system may be applied to, for example, optical films, optical lenses, goggles, skin care products, lighting, paints, adhesives, or panels.
