| titleOfInvention | Transparent Optical Article Having a Reduced Yellowness Appearance |
| abstract | 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 colour 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 colourless, 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. |
