What if you could go to sleep with a vision problem and wake up with a crystal-clear view of the world? A Spanish optometrist not only says this is possible, but he actually wants you to sleep in your contacts. His patented contact lenses, designed to achieve the same effect of corneal reshaping surgery, can correct vision defects like myopia (nearsightedness) and stigmatism – and now hyperopia (farsightedness) – without taking sharp instruments or lasers to your eyes.
Researchers in Australia have come up with an outwardly simple but incredibly ingenious way of curing blindness caused by corneal damage: Take everyday contact lenses, already used by millions (including me), and infuse them with a patient's own stem cells. After wearing them for about 2 weeks, test subjects reported a seemingly miraculous restoration of sight. Is it that easy?

Kaleidoscopic holograms like the ones stamped on your credit cards could soon wind up in the eyes of diabetics. Researchers at Smart Holograms in Cambridge, England, have devised a contact lens that changes shape in response to glucose found in tears—a direct indicator of blood sugar.
