    Abstract: The invention concerns a method of manufacturing an ophthalmic lens, comprising the steps of providing, mounting and blocking a substrate (10) on a machining support unit (65), surfacing an upper face (12) of said substrate, edging a peripheral edge (13) of said substrate, wherein said machining support unit comprises a surfacing member (40) and an edging member (30) which are separable, said surfacing member having a cavity (51) in which said edging member is located during said step of surfacing, said surfacing and edging members being configured so that said substrate is mounted and blocked on said machining support unit in a first predetermined position for the surfacing and the edging and, between said steps of surfacing and edging, the method comprises the step of withdrawing said surfacing member from said machining support unit by retaining said substrate on said edging member.

    Abstract: An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.

    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.

    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 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.
