> AFAIK, that the way our vision works is that our eyes only see a narrowly focused region in detail and the rest of our periphery is generated by our brain (based on what we saw there before). I know it's a over-simplification, but maybe too much of it? 100% of your periphery isn't "generated" by your brain based only on what you've seen before, otherwise it wouldn't be possible to see stuff "at the corner of your eyes" or "looking while not looking" where you can see stuff without actually focusing straight on on the thing itself.
