I read somewhere that the way most of us think of eye sight is wrong. For example, we may see a Facebook image and we believe that an image is made up of a 2d dimensional width by height image. And maybe our eye sight is constructed of moving 2d images. Is there a better way to describe how eye sight really works and how we may perceive light? The eyes are always moving and I guess sending certain signals to the brain with a feedback response to move based on what the eyes sees.

I am still trying to wrap my brain around DNA. It looks like the DNA strands contribute to the protein synthesis process. But how can we go to DNA synthesis to proteins to...a person's eye color being a certain color. Maybe it is the protein synthesis part that I am missing? Do the proteins created for the cell give the cell certain properties such that the cells making up the eye will have the color? Another question, do scientists know that this particular sequence of DNA contributes to protein generation for these particular cells. For example, is such that: DNA Sequence 1,2,3 contributes to eye color, etc? Is it that simple?
