Available
in several countries and soon to be in the
US, changing your eye color from brown to
blue doesn't involve adding the color blue
to the eye.
Dr. Gregg Homer, chairman at Stroma Medical’s
explained to CNN how it works: “The fundamental principle is that under every brown eye is a blue eye. The only difference between a brown eye and a blue eye is this very thin layer of pigment on the surface.
If you take that pigment away, then the light can enter the stroma—the little fibers that look like bicycle spokes in a light eye—and when the light scatters it only reflects back the shortest wavelengths and that’s the blue end of the
spectrum.”
The
laser procedure takes just 20 seconds. But because
it takes time for the body to remove the dead pigment
layer, the results of the new color wont be visible
for a few weeks. Preliminary studies have suggested that
the procedure is safe, but it will take several years for the clinical trials to reach completion.
