A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.

The invention relates to a binocular telescope comprising two tubes, which are connected in an articulate fashion with a swivel hinge pivotal around a joint bending axis. With a forehead contact unit comprising a comprehensive support device the binoculars can be supported in the area of the root of the nose or the forehead of the observer. The support device is here arranged at a body of the binoculars.

A lens apparatus includes a first optical system, and a second optical system disposed in parallel with the first optical system. Each of the first optical system and the second optical system includes, in order from an object side to an image side, a first optical axis, a second optical axis, and a third optical axis. When each of the first optical system and the second optical system rotates around an axis parallel to the third optical axis, a distance between first optical axes of the first optical system and the second optical system changes greater than a distance between third optical axes.
