NEW YORK -- A pair of glasses allows wearers to change their prescription, without even visiting a doctor.
"It's very cool technology, these are truly one size fits all," Dr. Christopher Starr explained to CBS This Morning. Starr is an associate professor of opthamology at Weill Cornell Medical Center.
The glasses can be adjusted from between -4.5 diopters for near-sighted assistance to +3.5 diopters for far-sighted vision. The glasses go for about $135.
