The extreme condition where a person has two of the irises or pupils in one eye is so rare that many believe that this is a myth…
Technically, there are no recorded cases with this disorder. Also, there are no photographs to support this. But, there are claims that there are people in the world with such problems. And if we believe this photoshoped photographs, they look like this.
Although, for the above mentioned disorder not one single case was documented, there are other conditions for which we have more than enough confirmation. As two examples, let’s take a look at heterochromia iridum where the irises are of different colors.
There is also a birth defect when there is a hole in the iris. What is even more tragic is the fact that most people with this condition are blind.
