Transparent optical article having a colorless appearance
Abstract:
The present invention relates to a transparent optical article comprising at least one dye at least partially inhibiting light having a wavelength ranging from 400 to 460 nm and at least one selective optical brightener that emits light by fluorescence at a wavelength ranging from 400 to 460 nm. The optical brightener acts as a means for at least partially balancing the color imparted to the transparent optical article by the dye, thus allowing for perception of said optical article as less yellow, and even colorless to an user or an observer.
