In a Nutshell

For years, I’ve shared my vision with a floater shaped almost exactly like Japan. Lately it’s been joined by an extra squiggle or two, plus a few drifting shapes I can only describe as pocket lint.

If you've ever watched tiny cobwebs swim across your sight and wondered what on earth they are, you’ve met floaters too, and we’re in good company. They're far more common than you’d guess. So I set out to learn what they actually are, and how worried I should be. Here's what I found.

Floaters: What are they, and should you worry about them?

Eye floaters are typically small clumps of protein or other material that drift around in the clear, jelly-like substance (called the vitreous) that fills the inside of your eye. When these clumps cast shadows on your retina, you see them as floaters in your vision. I mostly see them when lying on my back, reading a book, or staring at the clouds when I can think of nothing better to do.

For most people, floaters are just a natural part of the aging process (though I cannot recall ever having none). As we get older, the vitreous becomes more liquid and less jelly-like, causing it to pull away from the back of the eye. This can lead to the formation of those bothersome clumps.

While a little annoying, eye floaters are usually harmless and don't require any treatment. They may even come and go or settle out of your field of vision over time. However, in some cases, floaters can be a sign of a more serious eye condition, such as:

an eye infection or inflammation
bleeding in the eye due to injury or diabetes
a symptom following eye surgery (such as for cataracts)
a torn or detached retina (a medical emergency!)

If you suddenly notice a large number of new floaters, or if they're accompanied by flashes of light or vision loss, it's time to call your eye doctor, right away. These could be signs of a retinal tear or detachment, which requires immediate medical attention to prevent permanent vision loss.

In rare cases, eye floaters can become so numerous and dense that they interfere with clear vision. If this happens, your eye doctor may recommend a surgical procedure called a vitrectomy to remove the vitreous and the floaters in it. However, this is usually a last resort and is only considered when floaters severely affect your quality of life.

For most of us, though, eye floaters are just a minor annoyance that we learn to live with. Mine mostly disappear when I sit up to read, so it’s not a major problem in my case. The next time you spot those little guys drifting across your vision, just remember: they're usually nothing to worry about, but it never hurts to keep an eye on them (pun fully intended)!
