"Focal Points" -- The Discovery Files
By using eye-tracking technology to automatically control a pair of autofocus lenses, engineers have created a prototype for "autofocals" designed to restore proper vision in people who would ordinarily need progressive lenses. The autofocals are intended to solve the main problem with today's progressive lenses: They require the wearer to align his or her head to focus properly. The software in these autofocals fine-tunes the prototype's ability to keep its lenses in constant and perfect focus, regardless of the angle of view.
