Cup (1) for an eye-piece (2) of an optical viewing instrument comprises a wall (3) having an eye-piece connecting section (4) for connecting the cup to the eye-piece, an intermediate section (5) adjoining the eye-piece connecting section, and a light-protection attachment (6) connected to the intermediate section on the side facing away from the eyepiece connecting section via a partial section of the intermediate section, and a viewing opening (19) defined by the wall. The wall can be positioned in a first non-folded position for non-spectacle wearers to prevent stray light reaching the lens and in a second folded-over end position for spectacle wearers. The wall can also be positioned in a third stable ventilating position between the first and the second end position for non-spectacle wearers to prevent condensation on the lens. Preferred Features: The wall is made of a flexible plastic material or rubber material. |
