Scientists Create Electronic Glasses That Can Automatically Focus On Whatever You're Looking At

mmell writes: University of Utah scientists have created a prototype electronic lens which uses several technologies to customize the lens optics focusing on whatever the wearer is looking at. [Just like] the “oil lenses” in Frank Herbert’s Dune series of novels, the electronic lens (a transparent LCD) can have its index of refractivity modified by application of a small electric current. While I can conceive many uses for this technology (in spacecraft instruments, webcams/Handycams, handheld binoculars and telescopes for example), these were developed as a replacement for the progressive lenses — a.k.a. bifocals — which are worn by many with less than perfect eyesight. Many eyeglass wearers don’t tolerate bifocals well and I wonder if the adaptive optics in this prototype could relieve them of the need to carry multiple pairs of glasses? Whether they prove cost effective for the role of eyeglasses or not (and I can see no reason why they shouldn’t), the applications for this technology seem quite diverse and potentially even revolutionary. I wonder how long it will be before these are more than just a prototype?
