    Floaters, caused (I believe) by lensing of your aqueous humor (the liquid in your eyes) which is a viscous fluid. That’s why they show up more on bright solid color backgrounds (like the sky). As you get older, your eyeball fluid gets thicker and chunkier causing more of them.

    I don’t get these. Everyone else does and I don’t lol. Sometimes I see a flash of light in a spot. Pretty sure that’ll be an aneurysm in a couple decades.

      Right now I couldn’t see them even if I tried, from what I remember I saw them only when looking in bright light against solid color (white wall, blue sky, …) it’s not as solid as the image would suggest, it’s also WAAAAY smaller and more transparent

      When I got my eyes checked a few months ago, they where looking inside and asked me if I see a bright flash from time to time. I said that I do. They then said that if it increases in frequency, duration, or strength, I need to come in ASAP. They seemed concerned, but didn’t want to elaborate for my sanity.

        Bright flashes usually indicate a tear. Small ones can just be monitored but if you see a big flash (it’ll be sort of like lightning) and there is no environmental cause, it is an emergency. If you don’t get it repaired, you could go blind. This isn’t medical advice, just what I was told when I was younger. This article is basically WebMD quality, but gives a little more on what to look for.

            You didn’t. If you get a retinal tear and then don’t get treatment you’ll end up with permanent vision loss. It’s a major medical emergency. If all you had was a flash and nothing else, it wasn’t a retinal tear.

            Your doctors might be concerned about retinal detachment which can be just as serious though. If they think you’re a high risk for it it’s worth getting anything abnormal checked out.

        They are a lot more obvious if you look at bright surfaces, such as the sky, so one factor may be that you’re not outside as much.

        I don’t think they’re supposed to go away; rather the contrary, but who knows.

        One thing I do know though: if the amount increases noticeably, it could be a sign of something bad, so get that checked out.
