When I was little, I wondered what those little floaters in my eyes were. I'm not the only one! If you've seen little bug-looking dots and squiggles in your eyes, you're certainly not alone. They're often called "floaters," or "flying flies," though the scientific name for them is "muscae volitantes."
So what's the big deal? Do they pose any threat to our vision? It's better to first understand what they are and why they happen.
