In the United States, as of 2014, the only way to change eye color is to purchase color contact lenses. Laser surgery and iris implants are procedures available in other countries to change eye color, but they have not been approved for use in the United States.
Laser surgery to change eye color, unapproved in the United States, is available in other countries. Because all eyes are blue and any other coloration results from a different-colored pigment overlay, the laser procedure disrupts the top layer of color to reveal the blue color gradually. As of 2014, this procedure can change brown eye coloring to a shade of blue or green.
Iris implants are used in the United States on a case-by-case basis to treat people with congenital, acquired or traumatic iris defects. Iris implants can change eye color but can cause serious complications, such as cataracts and glaucoma.
