Different Colored Eyes Day

How boring would our world be if everyone had the same colored eyes? About 1% of the population has Heterochromia - the condition that causes different colored eyes.
Eye color often is the genetic trait that fascinates parents the most as a child develops. The colored part of your eye is called the iris. The pigmentation in the iris, melanin, is what determines your eye color.

Different Colored Eyes Day is a day to recognize an eye condition called heterochromia, which is most common in dogs, cats and horses but can occur in humans. People with heterochromia have different colored eyes. The difference in eye color may result from an injury or be a sign of certain diseases, such as Fuch’s heterochromic iridocyclitis, Horner’s syndrome or pigmentary glaucoma, especially if one of your eye’s color changes later in life. (Have your eyes examined if color change occurs!) Babies born with two different colored eyes should undergo an eye examination to make sure the heterochromia isn’t a symptom of a disease or illness.
However, sometimes heterochromia is completely harmless, and you’ll simply get to walk around with an extra unique eye color…or, colors.
Certain emotions can change both the pupil size and the iris color. That's why some people say their eyes change colors when they're angry or loving.
