I get this thing called visual snow where there’s a constant overlay of static like dots over your vision.
I only really notice it when I think about it but it’s much more distracting at night and when I close my eyes I never really see blackness.
It’s apparently possibly some sort of visual tinnitus.

I don’t think the question of when there is no pressure has been answered.
They think it’s because the cells in our eyes including the retina ( like all cells) emit a very small number of photons. In the light we don’t notice them as the receptors in the retina are being bombarded with so many photons. But in the dark the retina can actually detect these and interprets them as colours and patterns.
I’m sure someone in this thread already said this but please don’t put pressure on your eyes. The first thing I was asked when getting lasik was “do you rub your eyes?” And I had never given it any thought before and then I started to do research and it’s actually pretty bad to do it. Here’s an [article](https://visioneyeinstitute.com.au/eyematters/dangers-rubbing-eyes/) explaining why.
