If you look at a blank computer screen or even up at the sky, there’s a good chance you’ll see some weird floating globs in your field of vision. You can’t focus on them and they never stay still, but they’re there and they can be really annoying. What are they? Well, the clever animated video above explains just that.
The video also explains the phenomenon where you sometimes see dots of light shooting around in the sky with little dark tails.
If you want a full explanation, you’ll have to watch the video because paraphrasing medical jargon is not my specialty, but I can say that floaters in your eye don’t mean that you’re dying and there’s also not gunk on the surface of your eyes.
