(Cross posted from a PM as I wasn't aware that was against rules)
I've been browsing this site for a few hours now and saw many helpful posts from you, so I figured I could perhaps ask a general question that has been bugging me for a while now, but hard to describe.
For reference, I'm a recently turned 23-year-old male who has been anxious about my eyes for most of this year, as I only recently found out in February that it turns out I don't see as well as I always thought I did (ended up with -0.5 and -0.75, with 0.25 astigmatism in one eye). Of course, I went into a panic thinking perhaps this was a recent development and my eyes were getting worse. Research into myopia seemed to dispell that, though, and it is probably likely that I had this all my life (the tell-tale sign was noticing that slight streetlight starbursting in the distance at night was eliminated with glasses. I remember always having that and just thinking it was normal for lights to do that [and wow, there's a lot of detail to stuff in the distance I didn't know existed]). That, and the fact that as myopia is governed by your eye shape, it seems really weird that it would suddenly change for the worse now, right? That being said, I really hate glasses and just opt to go without, still, and I have no idea if PRK surgery would be suitable for such a minor correction.
Of course, because I was freaking out about my vision at that point, I also began noticing floaters, which an eye exam did confirm that they could see a few of them. Even typing this, I have an annoying grey little one whizzing by every so often. Those are the worst as they instantly show up as blurry specks in bright backgrounds, whereas the stringy like one I have is practically invisible unless I go looking for it. It will probably take a long time for me to ignore those ones considering my profession will have my staring into a screen for a majority of my life.
However, moving on to the actual question, I read about 'visual snow' and wondered if seeing something akin to that, but only in the dark was normal? It is hard to describe, as it isn't exactly obvious like camera ISO snow in the dark. It's similar to when you shut your eye and palm it, and your brain starts conjuring up all these wonderful colours and little snow like effects. That's basically what I'm seeing. Is that a normal side effect of the pupil dilating in the dark in order to receive more light? Is your brain trying to fill in the totally dark sections, resulting in that effect?
As you can probably tell from my blathering, I'm noticing every tiny little thing now and having it bother me. My days of thinking I was invincible coming to an end and realising I'm like everyone else is hitting me hard currently.
Any insight would be greatly appreciated.
