Nah. Our eyes don't use perspective projection. The back "walls" of our
eye balls are curved, not plain and flat. But even if they did use
perspective projection, our brain would surely account for it and
correct it, so that we didn't percieve things as distorted, even if we
could examine the edge our our field of vision.
