Why Do You See Stars When You Rub Your Eyes?

Ugh, my eyes are so tired. It feels like I've been staring at screens forever. And then, something strange begins to happen. Wait... why do I see stars when I do this? Let's find out. Inside the eye, the retina is lined with cells that turn light into tiny electrical signals. So those cells are what let me see? But pressure fools them. The cells fire as if light had arrived, even though none has. So my eyes are making their own stars! The signals race down the optic nerve to the brain, which paints them as light. Wow. It's like a tiny firework show, all inside my head. Phantom stars. Made by my own eyes. Those glowing sparks are called phosphenes, light seen without any light at all. Stay curious. ODDORA.
