  Optical material comprising a polymer matrix and at least one benzotriazole compound having at least one ester group, wherein said at least one benzotriazole is a chlorobenzotriazole compound that does not comprise any polymerizable group selected from allylic, acrylic and methacrylic moieties, or the optical transmittance through a 2 mm thick layer of said optical material is lower than 1 % for each light wavelength ranging from 280 to 400 nm, and higher than 65 % for light having a wavelength of 430 nm. This optical material can be used to protect from phototoxic blue light and UV light.

  The present invention relates to a transparent optical article (e.g. an ophthalmic lens) comprising a thermoplastic substrate and a dye at least partially inhibiting light having a wavelength ranging from 400 to 460 nm and an optical brightener for at least partially balancing the color imparted to the transparent optical article by the dye, wherein said optical brightener emits light by fluorescence at a wavelength ranging from 400 to 460 nm and is incorporated into a layer fused or bonded to the thermoplastic substrate. Said optical brightener allows for perception of said optical article as less yellow, and even colorless, to a user or to an observer. In addition, the UV-absorbers that may be present in the thermoplastic substrate do not negatively interact with the optical brightener.

  本发明涉及一种透明光学制品（如眼科镜片），包括热塑性基材和至少部分抑制波长为 400 至 460 纳米的光的染料，以及至少部分平衡染料赋予透明光学制品的颜色的光学增白剂，其中所述光学增白剂通过波长为 400 至 460 纳米的荧光发光，并结合到熔融或粘合到热塑性基材的层中。所述光学增白剂可使用户或观察者感觉到所述光学制品不那么黄，甚至无色。此外，热塑性基材中可能存在的紫外线吸收剂不会与光学增白剂产生负面作用。
