[T]he days of popping reading glasses on and off or constantly shifting your gaze through bifocals may be numbered. Researchers at the University of Utah have developed "smart glasses" with liquid lenses that can automatically adjust their focus.

"The major advantage of these smart eyeglasses is that once a person puts them on, the objects in front of the person always show clear, no matter at what distance the object is," says Carlos Mastrangelo, the electrical and computer engineering professor who led the research along with doctoral student Nazmul Hasan.

[...] 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.

The glasses come with a smartphone app, which uses data about the wearer's eyeglass prescription to automatically calibrate the lenses via Bluetooth. When the wearer gets a new prescription, they can simply update the information on the app.

    Judging from the photos in the article, they've still got a ways to go.
    Those prototypes look like something out of a Terry Gilliam movie.
