Has anybody's eye color changed ? if so did you feel anything changing in your eye ? how did it feel like ? what color did you have at first and what color did it change it to ? are you happy with your new eye color ? and when i mean by this i mean for real not eye contacts.

My eye color has changed. I didn't really feel anything changing in my eye, felt normal. I had a light brownish with like a hint of red and it changed to dark brown. Almost black. I'm pretty happy with it, nothing new for me. Just eyes but an advantage is to scare people... *heheheh*

Your eye color can change for sure!! But you don't feel it. It happens slowly over time. The change in eye color can happen for several different reasons. The one that most people are aware of would be eating a raw plant-based diet, that's when you get to see your "natural" eye color.
