Auto-Focus Smart Glasses Have Liquid Lenses

These auto-focusing smart glasses from the University of Utah use unique liquid lenses that adjust their focus.

According to researchers, these new smart glasses come with liquid lenses that can automatically adjust their focus, which means that you don’t have to take reading glasses on and off. This can also replace bifocals, which help you see through one prescription at a distance, and another for nearby objects.

“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,” Carlos Mastrangelo, the electrical and computer engineering professor who led the research with doctoral student Nazmul Hasan, told Smithsonian Mag.

Science fiction fans have been peering into the Internet for this device, having been prepared by Frank Herbert's 1965 Dune series. Consider the oil lens:

If the Kwisatz Haderach uses them, they've got to be good.
