Several independent internet sources say that green eyes are the rarest eye colour in the world. Does anyone know of a respected reference on eye colour to verify this properly ?
Dr. Joseph Allen OD FAAO (Doctor of Optometry) and (Fellow of the American Academy of Optometry)
Some notes I made from his video:-
The Rarest Eye Colors in the World - Eyes Colors ExplainedFrom the most common to the least common.
The rarest eye colour is Black eyes.
They have no eye colour, because they have no Iris and a condition called Aniridia. (Another source says their Iris didn't develop properly).
They are born with it due to a mutation on their PAX6 gene.
A few people will also develop Aniridia due to Trauma or Surgical Complications.
---------------
The second most rare Colour is Red or Red and Pink (less than 1%) and sometimes their Red eyes might also look Violet. They have a condition called Albinism, an inherited condition.
We were shown an example and their eyes were unforgettably striking
Red.
