when you push on your eyes you stimulate the same parts of it that detect light. Your eyes send this information to your brain as if it was normal light.
But it’s not, its useless information. Theres nothing to interpret, so you just get a weird mess.Its like when you would set an old CRT television to a non-existent channel. it would still try to pick up information, but instead all it gets is noise (static) It still tries to interpet it though, because it can’t tlel the difference

Your eyes are very delicate and sensitive instruments. Pressing them will physically stimulate the cells into firing off signals to the brains the same way getting smacked on the side of the head gives you ringing in the ears. FYI this is damaging to your eyes and prolonged or repeated presses WILL damage your eyes so you should avoid this or any aggressive rubbing.

The way I was always taught was that by pressing on your eyes, you’re increasing the pressure on your retinas, and cutting off circulation to the nerves the same way as when your leg falls asleep… It’s the visual equivalent of that ‘pins and needles’ feeling.
The difference is that your retina is much more oxygen-hungry than a random leg nerve and you can cause permanent damage if you do it too much.
