I realized at a young age that one of my eyes receives a more blue-shifted image and the other's image is more red. It's difficult to tell by rapidly opening/closing one eye at a time, but by using my fist positioned with my thumb resting on my brow between my eyes, then rolling it left and right quickly to cover up one eye and focusing on what I'm looking at, it's a stark difference. I do it every so often to see if it's changed with age.. I especially enjoy looking at the sky or white sheets of paper.
