A more accurate comparison would be if there was some sort of fucked up eye surgery which tried to paint over your natural eye colour by inserting colouring, but it left a shitload of scarring in your eye irreversibly altering your eye sight, used one eyelid in the process, caused 3 months of temporary blindness during recovery, and left like half of patients permanently blinded.
It also required the entire rerouting of your sinuses, so sometimes it even fucks with your hearing and your sense of taste and smell.
And there's John, insisting all these other fakers aren't legitimate eye colour changers, but that he always felt like a blue-eyed person and tried to commit suicide at 4 years old over his eye colour and that having blue eyes now is the only way he can function in society.
