Finally: Change your eye color -- with lasers!

The results of an early human trial are startling. Before-and-after photographs show that patients’ dark brown irises turned bright blue when they had been exposed to a targeted laser beam.

The Stroma device is likely to be available in South America, Asia, the Middle East and Southern Europe within the next 18 months, although a lot depends on the results of further human trials to check for safety as well as the need for an injection of a further £10million from investors.

But it could be 2015 before the invention is available in the U.S. and the UK, where more stringent safety regulations are in place than in other parts of the world.
