I see darkness, but when I rub hard I get various colors that are there as an after image when I open them again.

I was going to say something very similar to that, but I couldn't for the life of me remember what they were actually called. I tip my hat to you.

Sure it's ok to just say phosphenes....but where's the fun in that! Isn't it neat that everyone has slightly different ones?

To share my phosphenes, there are a few....yellow/gray haze, black with purple stars, red checkerboard rotation..

But the best, and the one that always fascinated me as a kid, was the grey/yellow...god...undulating? rotating rectangles? They almost look like prism tessellations..but on top of them, there are these black line images which cycle too quickly for my eye to catch them. I always wanted to be able to draw whatever they were, but they couldn't. Apparently the shapes are fairly constant if you can catch them, and there are papers hypothesizing that primitive cave drawings are these shapes...

Thanks for all the input everyone!

With me I first see a yellowish tunnel made of like a bunch of circles or something then after a few seconds I stop seeing the 'tunnel' and I now see this like circle that is hollow in the middle with a black filled with black the yellow will change in the circle and turn a blue colour then back to the Yellow. I don't know why I see this
