Could Contact Lenses be the Ultimate Computer Screen?
By Emma Woollacott
Imagine you have to make a speech, but instead of looking down at your notes, the words scroll in front of your eyes, whichever direction you look in. That's just one of many features the makers of smart contact lenses promise will be available in the future.
Imagine you're a musician with your lyrics, or your chords, in front of your eyes. Or you're an athlete and you have your biometrics and your distance and other information that you need. 
Research is underway to build lenses that can diagnose and treat medical conditions from eye conditions, to diabetes, or even cancer by tracking certain biomarkers such as light levels, cancer-related molecules or the amount of glucose in tears. 

Despite the excitement, smart lense technology still has to overcome a number of hurdles. One challenge will be powering them with batteries - these will obviously have to be incredibly tiny, so will they deliver enough power to do anything useful?
