This is one of things that were just pure sci-fi, before quietly cropping up in reality. The bionic lens, developed by a Canadian optometrist, could potentially enhance eyesight up to three times as much as what is currently considered perfect, or 20/20 vision, and would enable the wearer to actually zoom in on distant or tiny objects. These lenses are like your disposable dailies. They would be inserted into the eye surgically, in a procedure lasting less than 10 minutes. As an added bonus, the lenses wouldn't degrade, offering lifelong protection against cataracts and failing eyesight. There is also potential to integrate virtual reality and head-up displays, producing truly bionic vision.
