NATIONAL DIFFERENT COLORED EYES DAY – July 12
NATIONAL DIFFERENT COLORED EYES DAY
National Different Colored Eyes Day is observed annually on July 12th. There are many people out there that have two different colored eyes, and this is their day to celebrate!
Having two different colored eyes is a condition called Heterochromia. There are three types of Heterochromia:
- Complete heterochromia – one iris is a different color from the other.
- Partial heterochromia or sectoral heterochromia – part of one iris is a different color from the rest of the iris.
- Central heterochromia – an inner ring is a different color than the rest of the iris.
The concentration and distribution of melanin are what determines the eye color, specifically the color of the irises. The affected eye may be hyperpigmented (hyperchromic) or hypopigmented (hypochromic). The excess of melanin indicates hyperplasia of the iris tissues, whereas a lack of melanin indicate hypoplasia.
Most cases of heterochromia are hereditary, caused by a disease or syndrome or due to an injury. It is possible that just one eye may change color following certain diseases or injuries.
A few celebrities are known to have two different colored eyes include David Bowie, Christopher Walken, Dan Aykroyd, Jane Seymour and Mila Kunis.
HOW TO OBSERVE
Post on social media using #DifferentColoredEyeDay.
When you look at someone, what is the very first thing you notice? Is it someone’s hairstyle, their smile (or lack of one), fancy jewelry or outfit? Or is the very first thing you see is a person’s baby blues? If peepers are the very first thing you notice on people, you’re in luck. July 12 is Different Colored Eyes Day!
Heterochromia, two different colored eyes, is a trait commonly found in cats, dogs, horses and is relatively rare in humans. One eye can be blue, while the other is hazel. Or one eye may be brown while the other eye is blue. There are several different types of heterochromia – complete (the complete eye is colored), sectoral (two different colors in the same iris) and central (the iris has several colors.) While heterochromia can occur from an injury, disease or genetics, the result is a rainbow of colors right before your eyes!
While the origins of this annual holiday are unknown, chances are pretty good someone with this trait probably “invented” it. In fact, some familiar faces have different colored eyes.
