It definitely looks as if light was made specifically to be picked up by our retina. The way it travels as waves and collapses into particles upon observation is particularly astounding.
SB: It has nothing special to do with our retina, there were waves long before retinas. Waves have a way to turn from a gentle rotation, like light, or ocean waves, into particles that hit you hard when they collapse, are absorbed. Wade into the big surf on the beach, and get smacked.
light does not change speed upon reflection, coming or going from a mirror.
there was an ancient belief, that our vision was kind of a radar, we initiated sight by emitting some magical "light" (the biblical beaming eyes, ha ha) and saw only the return message. hope you do not believe a modern version of that error.
not that eyes do not reflect photons, (deers in the high beam) they have a double whammy upon , reflecting, leaving. this doubles the acuity of seeing.
radiation pressure is double upon reflection than absorbing,
