Seeing stars... in your own eyes? Why we get floaters.

February 10, 2024

Ever see those little specks, cobwebs, or even tadpoles drifting across your vision? Those are eye floaters, and while they can be annoying, they're usually nothing to worry about. But what causes these mysterious moving shadows?

The culprit behind floaters lies in the vitreous humor, a gel-like substance that fills the back of your eye. Imagine it as a giant bowl of Jell-O. As we age, this Jell-O starts to shrink and break down, forming tiny clumps of gel. These clumps cast shadows on your retina, the light-sensitive layer at the back of your eye, and voila! Floaters appear.

Think of it like looking through a slightly dirty window – the smudges might be distracting, but they don't necessarily mean the window is broken. In most cases, floaters are harmless and fade over time, or you simply get used to them.

​

However, there are some instances where floaters can signal a more serious issue. If you experience a sudden increase in floaters, accompanied by flashes of light, blurred vision, or a dark curtain closing over your field of view, seek medical attention immediately. These could be signs of retinal tears or detachment, which require prompt treatment.

​

So, the next time you see those floaters flitting about, remember, they're just a (mostly) harmless quirk of aging. But if they become bothersome or appear suddenly with other visual changes, don't hesitate to consult your eye doctor for peace of mind. After all, good vision is no small feat!
