If you've ever noticed little threads, dots or cobwebs drifting across your vision when you look at a bright sky or a white wall, you're in very good company. In one survey of smartphone users, about three out of four people said they see floaters. Most floaters are harmless, and for most people they fade into the background over a few months.
But a few features of floaters can mean something more serious is going on, like a tear in the retina. And from the patient's side, harmless floaters and serious floaters can look almost the same. I'm a retina surgeon, and these are the questions I hear about floaters in clinic all the time, so let's go through them together.
The short version
See an eye doctor the same day if you notice a sudden shower of new floaters, flashes of light, a shadow or curtain coming across your vision, or vision that's getting blurry. Even without those, new floaters deserve a dilated eye exam. And if your first exam is normal but your doctor asks to see you again, please keep that visit.
When should I worry about eye floaters?
See an eye doctor right away, ideally the same day, if you have any of these:
A sudden shower or increase in new floaters.
Flashes of light, especially at the edges of your vision, like lightning streaks or a camera flash.
A shadow or curtain coming across part of your vision.
Vision that's dropping or getting blurry. In the research, a change in vision is the single strongest warning sign of a retinal tear.
I'd add a fifth one: if you're worried about your floaters for any reason, go get them checked. And even without any of these big symptoms, new floaters are a good reason for a dilated eye exam.
If you can't get in with an eye doctor quickly, an emergency room at a hospital with eye doctors on call (often an academic medical center) is the best place to go. Many smaller emergency rooms don't have the equipment to look at the edges of your retina.
What are eye floaters?
Floaters are shadows. The inside of your eye is filled with a clear gel called the vitreous. When you're young, it's firm and clear, a bit like clear Jell-O. As we get older, it slowly breaks down and becomes more liquid, and little strands and clumps form inside it.
Light passes through the gel on its way to the retina, the thin layer of tissue at the back of your eye that senses light. Those strands and clumps cast shadows on the retina, and that's what you see drifting around. They tend to follow your eye movements and then keep drifting for a moment after your eye stops, which is why they seem to dart away when you try to look right at them.
What is a posterior vitreous detachment (PVD)?
Over time, the gel can pull away from the back of the eye. This is called a posterior vitreous detachment, or PVD. I like to call it a posterior vitreous separation, because patients understandably confuse a vitreous "detachment" with a retinal detachment, and they're very different things.
A PVD is a normal part of aging. It becomes more common with every decade, and most people have one by their seventies or eighties. When the gel separates, the strands shift and new floaters often appear.
Many people also notice one larger floater, often shaped like a ring or a loop. That's usually where the gel was attached around the optic nerve, and it's called a Weiss ring.
Why do nearsighted people notice floaters more?
If you're nearsighted, two things tend to happen. The vitreous often separates at a younger age, and floaters can be more bothersome, partly because a longer eye gives those shadows more room to look bigger by the time they reach the retina. In the smartphone survey, nearsighted people were about three and a half times as likely to describe their floaters as moderate or severe.
I'd love to hear from you: what do your floaters look like? Patients describe them in all kinds of ways, from bugs and hairs to cobwebs and tadpoles.
How often do new floaters mean a retinal tear?
Most of the time, a PVD is harmless. But sometimes, as the gel pulls away, it tugs hard enough to tear the retina. A tear can lead to bleeding inside the eye or to a retinal detachment, which can cause permanent vision loss. It happens often enough that we don't take new floaters lightly.
The numbers depend on who's being studied:
In general eye care, about 5 to 8 out of 100 people with a new PVD have a tear when they're first examined, according to the American Academy of Ophthalmology's current guidelines.
In retina specialist clinics, where the trickier cases get referred, it's closer to 1 in 7.
After a normal first exam, about 2 out of 100 people go on to develop a tear in the weeks that follow. Most of these show up within about six weeks.
One honest caveat: these numbers come from people who were worried enough to get checked. Plenty of people have mild floaters that settle down, and they never see an eye doctor at all. So if your floaters have been the same for years, chances are they're not an emergency. If anything about them changes, or you're worried, please get them looked at.
Why does finding a retinal tear early matter?
A retinal tear is how most retinal detachments start. Studies of untreated tears that cause symptoms suggest roughly a third to a half of them go on to detach. When a tear is found and sealed with laser or freezing treatment (cryotherapy), that risk drops to well under 1 in 10.
I'll never forget a night on call as a first-year ophthalmology resident at Washington University in St. Louis. We took calls about floaters all the time, and we had those patients come in at almost any hour. My senior resident and I examined one patient and found a tear in her retina. We took her into the laser room, and I watched my senior resident place laser all the way around the tear to seal it.
That was one of the moments I decided I wanted to be a retina surgeon. Most of the time, these symptoms don't come with a tear. For her, they did, and I was so glad we'd done a careful exam and could treat it right away. The laser didn't guarantee she'd never have another problem, but it started lowering her risk from that tear immediately.
It's always easier to treat a tear when it's small and caught early than after it has turned into a detachment. At that point, you're trying to catch the horse after it has already left the barn.
Why do I need a follow-up exam if my first exam was normal?
Because a small number of tears show up later. The current national guidelines note that about 2% of people with a normal exam at the time of their PVD develop a tear afterward, usually around four to six weeks out. That's why your eye doctor may ask to see you again even when everything looks fine. We call these serial exams, and their whole purpose is to catch the few tears that form in between visits.
And if your symptoms change before your next visit, please don't wait for the appointment. Call your eye doctor and get checked right away.
Do eye floaters go away on their own?
There's a little nuance here. The floaters themselves usually don't disappear. What changes is your brain. It's remarkably good at learning to tune out a signal that's always there, and over time it stops paying attention to the floaters.
In my experience with patients, well over 90% find their floaters bother them much less over about six months, often to the point they hardly notice them. That's a big reason we don't rush into procedures for floaters. It's probably also why some people feel that supplements or home remedies helped them, when it was really their brain adapting along the way.
What actually gets rid of eye floaters?
If your floaters are still really bothering you, getting in the way of reading, driving or work, there are two procedures. One is more definitive than the other.
Does YAG laser work for floaters?
YAG laser vitreolysis uses a laser to break up a larger floater, like a Weiss ring. In the largest randomized trial, photos showed the Weiss ring was dramatically reduced in most treated eyes, yet only about half of people said their floaters felt significantly better. More recent reviews find it's generally safe, with mostly temporary side effects, though there are still real risks and head-to-head trials are needed.
So if you're considering it, it's best suited to one big floater, and it helps to go in expecting roughly a coin flip on whether it makes a big difference for you.
Is vitrectomy for floaters worth it?
A vitrectomy is the definitive option. In the operating room, with your eye numbed or with you asleep, a retina surgeon places three tiny ports in the white of the eye and uses fine instruments to remove as much of the vitreous gel as is safe for your eye.
In a large international survey of retina surgeons, about 92% of patients were satisfied after vitrectomy for floaters. It's still major eye surgery, though, with risks that include retinal tears, retinal detachment, and cataract in people who still have their natural lens.
As a retina surgeon, I do vitrectomies for floaters, but carefully and case by case. It's built on several exams, a lot of conversation and trust, and clear expectations, so we're not adding more risk than it's worth. If you're interested, find a retina surgeon who does this procedure and have that conversation.
Do natural cures or supplements work for floaters?
These are the things I'd never spend money on: pineapple juice, castor oil in the eyes, and supplements marketed for floaters. None of the evidence shows they cure floaters, and the improvement people notice is most likely their brain's natural adaptation.
A few small studies of supplements look promising, but the ones I've seen have ties to the companies that make the products. I'd wait for independent research before recommending them.
What else can cause floaters?
Everything above is about floaters from the vitreous gel, which is by far the most common cause. Floaters can also come from inflammation inside the eye, bleeding in the eye from diabetes, and other conditions, some of which involve the brain. When in doubt, get a dilated exam from a qualified eye doctor.

Common questions about floaters
Are eye floaters dangerous?
Most aren't. They're usually a normal part of the vitreous gel aging. But new floaters, especially with flashes, a shadow or curtain, or blurry vision, can signal a retinal tear and need a same-day eye exam.
What are the warning signs of a retinal tear?
A sudden shower of new floaters, flashes of light, a shadow or curtain across your vision, and any drop in vision.
What is a posterior vitreous detachment?
A PVD is when the vitreous gel separates from the back of the eye. It's common with age and often causes new floaters. Most are harmless, but a few cause retinal tears.
Do I need a follow-up exam after new floaters?
Often, yes. About 2% of people with a normal first exam develop a tear later, usually within about six weeks, so keep any follow-up your eye doctor recommends.
Do floaters go away?
Usually the floaters stay, but the brain adapts. Most people notice them much less over a few months.
How do you get rid of eye floaters?
For most people, time. For floaters that still interfere with daily life, YAG laser and vitrectomy are options, each with trade-offs to discuss with a retina specialist.
