I get this but only before a migraine headache. It is a warning to me that one is coming on. I get total vision loss of my central vision (everything I look at directly is completely black) or a loss of peripheral vision (sides of vision field are totally black) . I do get wavy lines and like snow vision before that happens. Do you have this vision problem constantly? When I accidentally overdosed on Tylenol due to my chronic pain and forgetfulness (inability to manage my own medication) I had the exact kind of vision problem you are explaining and it was constant. It was due to my body being toxic. Liver was failing. Are you taking medication? You mentioned partying. Maybe you are overloading yourself with toxins. I am now healed from liver and kidney failure (yeah! This almost killed me). Seriously, I had a near death experience and everything. But now I have some vision distortion like if I see a patterned rug I might think one of the colors is a piece of paper instead of part of the rug, just things like that now other than when I have the migraines. That is the only advise I have for you. Try drinking a lot of water, could also be you are dehydrated. Good luck. I know how
bothersome that is.
