“You ever got that checked out by a doctor? Heterochromia has strong links with some genetic diseases and/or susceptibilities afaik. Visually great, though!”

“My parents told me that my birth was a bit complicated. In the end, I got ‘pulled out’ with some sort of pliers. Almost all of my left body half had a bruise, even my left eye. I think that caused the pigments in my iris in that part not to form. I recently visited my mothers‘ and brothers‘ eye doctor, and he said that my sight is in no way impaired. The only differenceInotice sometimes is, that when I close my right eye, everything has some sort of a brighter tint.”
