The Smithsonian brings to attention the work being done by the University of Utah on prototype "smart glasses" that, by using liquid lenses, are capable of quickly changing focus depending on where you're looking. Above, a photo of the glasses in the hands of Carlos Mastrangelo, the electrical and computer engineering professor who led the research. The photo is credited to the University of Utah.

The new smart glasses consist of lenses made of glycerin, a thick clear liquid, enclosed in flexible membranes. The membranes can be mechanically moved back and forth, changing the curvature of the glycerin lens. The lenses are set in frames containing a distance meter on the bridge, which measures the distance from the wearer’s face to nearby objects using infrared light. The meter then sends a signal to adjust the curve of the lens. This adjustment can happen quickly, letting the user focus from one object to another in 14 milliseconds.
