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.
