A question about my eye color?

Question

Okay, I had brown eyes, I'm 14, and for the last month they've been going dark green why?

Answer 1

The exact same thing happens to me. Apperently, it's because I was born with weird shaped eyeballs. Most people have spherical eyeballs whereas I have rugby (American Football) shaped eyeballs.

P.s: i'm not sure what the shape of my eyes has to do with them changing colour, but that's what the doctor told me.
