    • The invention proposes an active system of vision (20) for a wearer comprising: -a first and a second customizable ophthalmic lenses(22) mounted on a spectacle frame, each customizable ophthalmic lens being adapted to be disposed in front of one eye of the wearer and having an electrically variable occultation between a first light occultation state,substantially transparent, and a second light occultation state,substantially obscured; -an identification device (32) adapted for identifying the wearer's viewing state among at least a near vision viewing state when wearing the first and the second customizable ophthalmic lenses,a near vision viewing state being defined for viewing distances equal to or lower than 60cm;and -a processor (40) operatively connected to each of the customizable ophthalmic lenses(22) and to the identification device(32), wherein the processor is configured to: ⋅ switch the electrically variable occultation of one of the first and the second customizable ophthalmic lenses (22) from the first light occultation state to the second light occultation state when a near vision viewing state (NVVS) is identifiedby the identification device whilst at the same time the other lens is or return in the transparent state;and ⋅ control the electrically variable occultation of the first and the second customizable ophthalmic lenses (22) such that they are in the first light occultation state when the wearer's viewing state is identified as being different from a near vision viewing state(NVVS) by the identification device (32).
    • 本发明提出了一种用于穿戴者的主动视觉系统(20),包括: - 安装在眼镜架上的第一和第二可定制眼科镜片(22),每个可定制的眼科镜片适于设置在眼镜的一只眼睛的前面 佩戴者并且在第一遮光状态(基本上透明)和第二遮光状态之间具有电可变遮蔽,基本上模糊; - 识别装置(32),其适于在佩戴所述第一和第二可定制的眼用透镜时在至少近视觉观察状态中识别佩戴者的观看状态,近视觉观察状态被定义为等于或低于60cm的观看距离; 和处理器(40),其可操作地连接到每个可定制的眼科镜片(22)和识别装置(32),其中所述处理器被配置为:·切换所述第一和第二可定制的 当通过识别装置识别近视觉状态(NVVS)同时另一透镜处于或返回透明状态时,从第一遮光状态到第二遮光状态的眼科镜片(22) 第一和第二可定制的眼用透镜(22)的电可变掩蔽使得它们处于第一遮光状态时, 识别装置(32)将rer的观看状态识别为与近视觉状态(NVVS)不同。
