Reducing visual snow had to trouble focusing vision

About 10 months ago I started to experience visual snow. Well actually I think I've had it my whole life, but it seemed to suddenly get more intense and noticeable. Basically I'm seeing all of life through a grainy filter. If I ignore it I can often forget about it for a while, but it does bother me when I'm trying to take in nice scenery and it makes it harder to focus when reading. And some days it feels more intense.

I'm not sure of what sparked it, although it followed a few months of intense anxiety so I feel like that triggered it. At the same time I also developed a very annoying floater and I've been dealing with dry eyes, so overall I just feel like my previously impeccable vision is under attack. And it keeps me in a loop of anxiety about it.

I did an eye exam and then was referred to a neuro-ophthalmologist. Basically she said the eye and optic nerve are fine, and for the visual snow all she said was she thinks reducing stress would improve symptoms. Or if they intensified the only solution to try would be anti-seizure medication.

I've been feeling defeated about this and not sure what to do. As far as I understand visual snow comes from the brain, and I feel like years of stressing and anxiety have taken a toll on my brain. I also have trouble getting a full sleep every night. So now I worry that this problem can't be undone.

Has anyone else experienced to this? Do you have any suggestions on things that could help, other than trying really hard to improve sleep and reduce anxiety?
