Humans do this, but we have more senses to corroborate which leads to better error checking. But what you see in your visual mental space is not reality. Your brain makes a boatload of assumptions. To test this, research what happens during saccades and how your brain "rewinds" time. Or try to find your blind spot by looking at different patterns and noticing when your brain fills in the gaps at your blind spot. It will recreate lines that aren't there, and dots will wholly disappear. Additionally as an anecdote, I have noticed plenty times that when I misread a word or phrase, I usually really do "see" the misspelling, and only when I realize the misspelling does my brain allow me to see the real spelling. I first noticed this phenomenon when I was a child, and because I have a vivid visual memory, the contrast is immediately obvious once I see the real phrase. Additionally, I seem to be able to oversharpen my vision when I focus, making myself hyperattentive to subtle changes in motion or color. The effect can be quite pronounced sometimes, reminiscent of applying am edge filter. It's clearly not reality, but my visual system thinks it is. If you really want to understand how much the visual system can lie to you, look into some trip reports from deleriants on erowid. I wouldn't recommend to try them yourself but I will say that nothing will make you distrust your eyes and ears more. It's basically simulated hallucinatory schizophrenia and psychosis.
