Augmented reality glasses

AR glasses means "augmented reality glasses". They are see through display glasses. They are buzzwordy.

AR means a display that shows virtual content that moves in 3D in the environment that is overlayed upon it.

It was rumored that Apple was going to release AR glasses. The rumors spread in the year 2019.

The highest form of AR glasses is a set of glasses with virtual content registered to the real world environment.
