I had these plus other vision issues like snow vision (black and white fizzy vision over everything, really bad even in the dark). I was convinced I was going to go blind over the years. And I used to think there were huge spiders everywhere some black spots I saw were so big. It was distressing every twenty minutes getting shocked like that. Got worse during pregnancy! Or when taking some medications, or not sleeping more than 4 hours. Saw optician and was referred to hospital but got the all clear, told just live with it. I just got used to it after a while. I also have tinnitus so was used to putting up with annoying things (took me years to habituate to the screaming in my ears!) so the eye thing was not so bad in comparison and I adjusted over a much shorter period of time.
My eye problems almost completely resolved though once I improved my health including addressing all nutritional deficiencies and hormone imbalances. I don't see anything weird in my vision anymore except maybe some mild snow vision if my diet and sleep is off plus if I take certain medication. But it soon dies down when everything is back on track again. I didn't try to cure anything eye related, it was just another happy outcome of everything I began doing.
Things I was very deficient in included vitamin A (I take carlsons 15,000 IU palmitate every other day so don't get too much) all the B vitamins, D3, vitamin k, magnesium, protein and progesterone. I used good quality supplements as well as good quality food for these things. I also take coconut oil which helps thyroid. I wouldn't say it was just one thing which helps as everything in the body works synergistically. Eg progesterone and thyroid help each other, you need vit d3 for progesterone etc etc So I'd say everything I did played a part. Any kind of stress hormone also impacts my vision. Keeping in a calm state, whether through mindfulness or forcing it via supplementing things like progesterone, Niacinimide, L Theanine, also played an important part.
Maybe this will help some people with similar eye problems who end up here. (It also helped my tinnitus. It's not as deafening now. I've discovered taking lots of coconut oil suppresses it a little further too.)
I'm always amazed at how the body can heal given the right tools.
