Abstract: Electro-optical glare protection device comprising a liquid crystal (LCD) and an electronic control circuit (75) for controlling same, whereby a plane-parallel liquid crystal cell (LCD) is joint face to have at least on one side with a plane lens (33, 34, 37, 33, 42, 43, 46, 47, 52, 53, 56, 57) in order to form a neutral lens (31, 35) or an ophthalmic lens (41, 45, 51, 55) and in particular a multi-focal or progressive lens. This electro-optical glare protection device is preferably operated in a “normally-black” mode and comprises a wearing-switch (78) which detects whether the anti-glare device is worn or if it is pushed aside or put aside.
