&gt;simulate vision using eyes not camera lenses. 

You mean my eyes don't naturally have film grain?

Well *acktually*, the human eye also suffers from visual noise, quite similar to a film camera's. We're just often not focused on one spot long enough to notice it.

When in a pitch black room though, you can see it fairly well since there's nothing else to focus on.
