Seems pretty dumb in our biological design to not be able to regenerate such a functional (and also easily breakable) part of our body.

      The idea is that if you can make your surroundings as dark as possible, then shine a very small point of light into your eye and wiggle it so there’s a shadow changing angles rapidly across your retina, this will make the blood vessels you can’t normally see shift slightly in your field of vision so your brain forgets how to edit them out and they pop into view.

      This site gives instructions how to use black construction paper with a pinhole in a dark room, but I’ve learned how to do it with a nearly closed fist and any bright light source.

        So its kinda like how your brain edits your nose out but if you close and open alternate eyes fast it has a hard time doing that?

          Yep! Or even how you usually breath without thinking about it but can take over manual control. Your brain does a LOT of things with your senses all the time that you don’t notice, it has layers and layers of intelligence that makes decisions on what it will “report” upwards, so you depend on basically a vast system of managers or sub-officers that are conscious but have no language, to fully captain and control your meat-ship.
