    摘要： 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.

    摘要： A transparent optical element with dual light-polarizing effect comprises a first film forming a linear light-polarizer in a first surface portion of the element, and a second film forming a retarder plate within a second surface portion. The second surface portion is contained in the first surface portion. Such element may form an eyeglass adapted for providing stereoscopic vision by light polarization selection in the second surface portion, while providing protection against excessive light intensity in the first surface portion.
