The end of bifocal glasses

11 Apr

Researchers at the University of Arizona have created glasses that can adjust the perscription in the glass dynamically as your eyes move.

“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.

“The lens is ‘switchable’ between two states. The wearer has a whole picture for viewing,” Li said in a telephone interview.”
