NATIONAL DIFFERENT COLORED EYES DAY
Each year on July 12, people across the United States celebrate National Different Colored Eyes Day. There are many people out there that have two different colored eyes and today is their day to celebrate!
Heterochromia of the eye: Two different colored eyes. Heterochromia is of two kinds;
- 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 it remainder.
The concentration and distribution of melanin is 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 that are known of having two different colored eyes include David Bowie, Christopher Walken, Dan Aykroyd, Jane Seymour and Mila Kunis
