National Different Coloured Eyes Day
Celebrate those who have two different coloured eyes on #NationalDifferentColouredEyesDay
12 July is National Different Coloured Eyes Day, a day that is observed annually to give the many people out there with different coloured eyes a chance to celebrate!
Having eyes of different colours is a condition called heterochromia, of which there are three types:
• Complete heterochromia – one iris is a different colour from the other.
• Partial heterochromia or sectoral heterochromia – part of one iris is a different colour from the rest of the iris.
• Central heterochromia – an inner ring is a different colour than the rest of the iris.
Melanin – especially the concentration and distribution thereof – determines eye colour, specifically that of the irises. The affected eye may be hyper-pigmented (hyper-chromic) or hypo-pigmented (hypo-chromic).
An excess of melanin indicates hyperplasia of the iris, while a lack of melanin will indicate hypoplasia.
Most cases of heterochromia are hereditary, or caused by a disease or syndrome, but they can also be due to an injury. It is possible that just one eye may change colour following certain diseases or injuries.
There are a few celebrities who have different coloured eyes, including David Bowie, Christopher Walken, Dan Aykroyd, Jane Seymour and Mila Kunis.
