Does change my eye color really work? The short answer: no. The pigment melanin determines your eye color. Eyes with a lot of melanin will be naturally darker. The less melanin in your eyes, the lighter they’ll be.
Can a person change their eye color naturally? Can it really change for no apparent reason? In most people, the answer is no. Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age.
What is the rarest eye color? Of those four, green is the rarest. It shows up in about 9% of Americans but only 2% of the world’s population. Hazel/amber is the next rarest of these. Blue is the second most common and brown tops the list with 45% of the U.S. population and possibly almost 80% worldwide.
Can brown eyes turn green? If the color of one or both eyes changes suddenly and significantly, see an eye doctor as soon as possible. It is particularly dangerous for eyes to change from brown to green, or from blue to brown. Major changes in the iris’ pigment can indicate illness, such as: Horner’s syndrome.
