Laser Procedure Can Turn Brown Eyes Blue


     From many famous actors and actresses, we have seen that a very popular eye color tends to be blue. Blue is send to represent a sign of attractiveness. Many studies have shown that people with blue eyes tend to stand out more in a crowd then people of different eye colors. In the past. the only way to change the appearance of your eye color was using different color eye contacts. Now there is a medical procedure that allows to change people with brown eyes to the color of blue. Pioneered by Stroma Medical, the laser procedure works by eliminating the brown melanin that's present in the anterior layers of the iris. "The fundamental principle is that under every brown eye is a blue eye," Dr Gregg Homer told CNN, adding that there is no actual blue pigmentation in the 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."This  effect is similar to showing why are sky is blue. According to the medical board, this form of surgery is said to be safe as they use low intesnity lasers which are not very harmful. The procedure is said that it will cost $5,000.
