Bailenson and other Stanford researchers tested out the Meta Quest 3, a “mixed reality” headset that lets people blend physical and virtual worlds. While the headset is different from AR glasses, the gadget can display real-time video of a user’s surroundings in the physical world.

The AR glasses aren’t available to the general public, but that hasn’t stopped criticism over the gadget’s limited battery life and field of view.

Sticking their goal of tech-augmented eyesight, the makers of the popular photo app Snapchat have launched their latest pair of glasses that can superimpose digital objects into real environments. The new generation of "Spectacles" with transparent lenses offers better display quality and faster response times.

Snap on Tuesday, September 17, introduced its fifth-generation augmented reality glasses, Spectacles, designed to overlay digital graphics onto the real world. These glasses are currently only accessible to developers who are willing to pay a monthly subscription fee of $99 for a year.
