A US doctor has claimed that brown eyes could be turned into blue through a simple 20-second laser treatment procedure.
Dr Gregg Homer of Stroma Medical, a clinical equipment company based in California, declared his new “Lumineyes” treatment could be a permanent alternative to coloured contact lenses, the Telegraph reported.
Brown eyes, the most common type across the world, appear so because of the layer of pigment at the front of their eye.
People with blue eyes also have melanin, but it is concentrated at the back of the iris rather than the front, meaning the eye absorbs longer wavelengths of light while reflecting shorter ones.
The treatment uses a laser to remove melanin, the brown pigment, from the upper layer of the iris, leaving the blue colour free to replace it within two to three weeks of the procedure.
But the process is irreversible because the melanin will not grow back and cannot be replaced.
The cosmetic operation would cost about 3,000 pounds and could be available in countries outside America within 18 months, said Dr Homer, a former entertainment lawyer.
“A blue eye is not opaque, you can see deeply into it, while a brown eye is very opaque. I think there is something very meaningful about this idea of having open windows to the soul,” he told KTLA Morning News.
But the Daily Mail reported that clinical trials have yet to be completed.
