    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 was born with VS, never seen a clear image in my life. Ironically very into AV stuff and chase the highest quality picture. I often lament that I’ll never experience perfect quality and clarity because of my VS

      Born with tinnitus too! The double whammy haha

        I’ve got tinnitus too. Mine is not disturbing in the morning but gets really loud in silent rooms, so loud it sometimes disturbs my sleep. Interestingly enough, I’m interested in hifi

        Both VS and tinnitus are not professionally diagnosed though and they are the least of my concerns. ADHD and asperger’s (both professionally diagnosed and treated to some extent) is what affects my life most

      Visual snow on a blue background is extremely common. It’s called the blue field entoptic phenomenon and basically everyone can see it if they try to

    Those are so cool. They’re the only way (I know of) that you can see molecules with your naked eye. Actual molecules! That’s practically at the level of atoms, and you can see that microscopic stuff!

    **Edit: they are not, in fact, molecules. See replies for more info. **

    Also red blood cells. It’s pretty cool that if you stare at the sky (not the sun; please not the sun) you can sometimes see red blood cells move in the back of your eye. Single cells! Amazing.

      Err, I don’t think that’s right. That’s physically impossible. Only electrons are small enough to visualise molecules and atoms, which is why you need electron microscope to see those.

        Whoa, my optometrist told me that’s what they are and now I’m really disappointed.

        Considering their shape and what you said about them being impossible to observe in visible light… I guess those branch-like pieces are cell organelle fragments instead?

        Dang, and here I was excited to be seeing molecules.

      They are individual cellular organisms but they’re not molecules. Individual molecular structures are too small for light to interact with so no matter how much you magnify them you’re never going to see them.

      That’s why things like electron microscopes were invented. You can’t just build bigger and more powerful microscopes it doesn’t work.

    That’s your eyeball slowly detatching itself from its socket because your don’t spend enough time outside.

      Thats not what they are or how they work EXCEPT incases where you suddenly see them all the time regardless of light conditions.

      It’s interesting that the view isn’t horribly pixelated due to too much screen time. Anon must like books or something…
