Visuals from pressure on eyes.

I smoke a lot so I end up with dry eyes, I'll rub them and you can see some pretty crazy fractals. Anyone else see this? What do you think it is? I couldn't really find much info.

What you are experiencing is propably entoptic phenomena. Thats the fancy way of saying visuals that the source is the eye itself. They could be categorised as phosphenes, which are visual phenomena that arise when the eye is stimulated by other stimuli than light :for example pressure (rubbing). While the eye generates them, its up to the brain to "make sense" of them hance they can appear in many forms -from simple dots to even organised geometric shapes.

Yeah, James Kent who wrote Psychedelic Information Theory also said that it's pressure phosphenes.

 

[BananaForeskin]

Yep, simply because of the pressure. Theoretically happens to everyone.

I get dim, intricate spider web patterns in a sea of floating grey and red noise. Not really an avenue i want to pursue further though - I value my eyes!

Ya, it kind of looks like the design on my eye with little dots of color and stuff. It's cool to put a name to it though. entoptic phenomena, Phosphene.

Is it bad for your eyes? I do this quite often and always assumed it wasn't good for my eyes, but is it actually bad for them? Usually I get a slight vision impairment afterward, but it fades away. Similar to how if you stand up too fast your vision goes black sometimes and then slowly comes back.
