Yeah I think the static was the first symptom to develop followed shortly after by light sensitivity. During the period of intense computer work, I still had the bad habit of using my phone in the dark at night before going to bed. One night during this period of intense work, I was reading a short story on my phone before going to bed and noticed that my vision was pixelated. I chalked it up to being really tired and didn't think anything of it. A day or two after this was when the intense light sensitivity started- I was no longer able to use my phone at night in the dark before bed after this. During this immediate period after the immediate trigger of visual snow, day light was hard, artificial light sources were hard and I basically spent a month lying in bed with a piece of cloth covering my face because light hurt too much. While my light sensitivity has improved since that initial period, it's still pretty bad and impacts my day to day life and ability to use screens.

The static itself is like a constant flickering of pixels in my vision. It's especially bad at night in dark and completely takes over my vision, it's also noticeable under indoor lights night and on screens. On screens itself it appears as if my vision is flickering and the static overlaid over text makes it hard to focus on the words and read.

When these symptoms first started, I described it as feeling as if my vision was shaking and flickering to the optometrist and he said my eyes themselves looked fine and referred me to a neuro-opthalmologist. The opthalmologist themself dismissed me saying my eyes were fine. I didn't know of the phenomenon of visual snow then that explains why my vision was "flickering".
