@jasonfullerton7763 Optics was given when you were around 12...Last time I checked, it's not even in the program or only flat mirrors. We had curved mirrors, lenses and mediums with different density...Oh and we were given to play with lights that were "shaped" through a slice and then lasers. Now, I never used any of that knowledge :-D

@christo930 That's because you are not yet aware of how fast your eye move. Yes, it does move really quickly. On top of that, even when "stationary", your eye is a lens. So rays come in all directions. So you look at more than you believe ^^
