Eli5 why does pressing my palms against my eyes create a kaleidoscope effect?

Beware incorrect answers to this, ie ones that say it’s harmless. I worked in retinal ophtho for some years and was actually warned against doing this. A retinal specialist saw me rubbing my eyes at the nurse station and scolded me about how it’s applying pressure to my retina and optic nerve. That’s why you get the colors and patterns too – from mechanically applying force to these photo-receiving cells. And let me tell you from experience, the retina and optic nerve are about as delicate as our anatomy gets. So from then on, when I rub my eyes, I’ve only applied pressure to the orbital bone
thank you! i have really wanted to know the answer to this but didnt even think to ask here.

When I was little, nobody had told me this. I am/was kind of stupid.
I legit thought I had super powers and could see the future/unknown things. I was 7 or 8 and I would spend hours practicing my powers…I would take a card from a deck, push on my eyes until I thought I knew if it was red or black and I was convinced I was almost always right.
After lots of training, I showed my Dad. He called me stupid and told me to say the full card name. Of course I couldn’t.
Do **not** do this, it can cause permanent damage such as Keratoconus, leading to requiring corneal transplants. It’s not worth it.

The cones and rods in your eyes respond to and code “sight” from detecting pressure from teeny tiny light wave-particles. When physical pressure is applied from your palms (don’t do this!) to the sclera, a similar sort of sensation is relayed to your optic nerves and you “see” colors. There are tales of Isaac Newton poking his eyes with needles to understand optics. Again, don’t do this. Probably not super healthy.
