High-tech contact lenses are straight out of science fiction — and may replace smart phones
Contact lenses are the result of an accidental discovery made during the Second World War. Ophthalmologist Harold Ridley noticed that despite acrylic plastic shrapnel shards becoming embedded in the eyes of fighter pilots, it did not appear to cause any harm. This finding eventually led to the creation of hard intraocular lenses for the treatment of cataracts. Over the years, new scientific discoveries have led to softer and more comfortable contact lenses. And now, research bringing together chemistry, biology and microelectronics is resulting in contact lenses that are straight out of scie...
