A team of researchers at the University of Arizona said Tuesday that they have developed a liquid-crystal eyeglass lens that can automatically change focus depending on the line of sight of the wearer.

Guoqiang Li, assistant research professor of Optical Sciences of the University of Arizona and member of the team of scientists, said the technology could help provide a viable alternative to bifocals, glasses often associated with grocery stores and old age.

I hope this gets some serious funding, why? This is the first step to replacing all/most conventional display devices, with either eyeglass based, or implant based displays. Augmented reality will take off.

Sound promising - not only for bifocals, but especially for 3D glasses!
A 3D shutter / VR glasses solution that doesn't make your head hurt after 30min - that would be really awesome...
