Its very subtle, but I was reading a post about all those people who see a ''warm'' tone in one eye and a ''cold'' tone in the other, all saying they've had it since childhood and no one had a answer why. I tested and realised I can notice this difference and remembering noticing it when I was younger too, I'm 23 now and have been to a ophthalmologist every 6months-1 year all my life and although I've never brought it up, they've never said anythings wrong. I asked my partner if she could and to my surprise, she said one eye sees ''cooler'' colours and they other sees ''warmer''.. this is all slight, not noticable unless it's on a blank wall and hyper-aware. any answer?
