Hey there, for months I am trying to wrap my head around how eyes really work. My eye has a retina that receives photons that trigger my nerves to create a certain color for that location. Why do photons from different angle not seem to alter the image that I am seeing?
For example, if I look at an infinitely large white wall with a small red square in front of me, photons from the red square would “tell” my eye that the square is red at that location, but shouldn’t other photons bouncing off the white part of the wall hitting the same retina cells provide the information that the color is “white”? It looks like my eye is able to only process photos that come straight at it. Is that correct and how is that?
I hope this question makes sense.
Thanks a lot.
