'''Optical head-mounted display''' or '''OHMD''' is a type of [[head-mounted display]] that projects images and allows the user to see through its display. OHMDs are used in [[augmented reality]] (AR). Unlike [[head-mounted display#Virtual Reality HMDs|~~Virtual Reality~~ HMDs]] that ~~obscures~~ our vision of the real world, OHMDs allow us to see our surroundings while streaming data and image overlays in front of our eyes.

'''Optical see-through head-mounted display (OST-HMD)''', also called '''Optical head-mounted display''' or '''OHMD''', is a type of [[head-mounted display]] that projects images and allows the user to see through its display. OHMDs are used in [[augmented reality]] (AR). Unlike [[head-mounted display#Virtual Reality HMDs|virtual reality HMDs]] that obscure our vision of the real world, OHMDs allow us to see our surroundings while streaming data and image overlays in front of our eyes.

Optical head-mounted display can cover only 1 eye such as the [[Google Glass]] or both eyes. Wearers can interact with the projected digital content through input methods such as voice commands, gestures and controllers.

The focus of OST-HMDs such as the Hololens and Magic Leap 1 is usually set to about 1 or 2 meters in front of the face.

[[Vuzix]] is a provider of OST-HMDs.

A number of companies have marketed [[waveguide]]s for OST-HMDs, including [[Dispelix]], [[Digilens]], and [[Lumus]].
