Hello everyone, I honestly can't find a place where I belong as there is no independent site for palinopsia only and this seems like one of the only places where I can ask about my trails. I am sorry. I don't actually have Visual snow but I had the trails for many years now (possibly 4 years). I don't have any other visual symptoms other than high order aberrations from dry eyes and I have 20/13 vision. I have a few questions as I do fear about developing visual snow. I didn't do any drugs/medications and I have pretty good health. 1. Will having trails for years cause VS? 2. Is 4 years enough time to get all of the other visual snow symptoms? 3. How long does it usually take to get other VS symptoms as soon as the first one starts? Thank you.
