Earlier this month, the BBC reported that a US doctor is trying to pioneer a laser treatment that changes patients' eye colour.
Dr Gregg Homer claims 20 seconds of laser light can remove pigment in brown eyes so they gradually turn blue. The process involves a computerised scanning system that takes a picture of the iris and works out which areas to treat. The laser is then fired, using a proprietary pattern, hitting one spot of the iris at a time. When it has hit every spot it then starts again, repeating the process several times. Dr Homer is now seeking investment of up to $750,000 (£468,000) to continue clinical trials.
However, other eye experts are urging caution because destroying eye pigment can cause sight problems if too much light is allowed to enter the pupil. "The pigment is there for a reason. If the pigment is lost you can get problems such as glare or double vision," said Larry Benjamin, a consultant eye surgeon at Stoke Mandeville Hospital, in the UK.
But why go through this? Experimenting with different eye colours is lots of fun and can really change your appearance. But this can be done as simply as picking up a new pair of coloured contact lenses. Blue, green, hazel; it's so easy to achieve with the selection offered by GetLenses. You don't even need a prescription in some instances.
