What Eye Floaters Mean and When You Need to See an Optometrist
Do you see wispy threads, cobwebs, or dark specks that seem to drift in front of your eyes? Called "eye floaters," these moving shapes are often harmless, although their presence can indicate a serious eye problem in some cases.
What Are Eye Floaters?
Eye floaters are small clumps of protein floating around in the vitreous of the eye. The vitreous is the gel-like material inside that eye that helps the eye maintain its shape. As you age, the vitreous shrinks slightly and pulls away from the back of the eye. Strands of collagen clump together when this happens. Depending on their size, the clumps may be barely noticeable or might interfere with vision. Because the clumps appear to float in front of your eyes, they're commonly called "floaters."
Floaters are most obvious when you look at the sky or another bright and/or plain background. According to the Cleveland Clinic, most people first see floaters at age 50 or older.
Floaters can look like:
- Cobwebs
- Strings
- Lines
- Dots
- Rings
- Spots
- Specks
- Smudges
- Dark Circles
You may be more likely to develop floaters at any age if you are extremely nearsighted, have diabetic retinopathy, had eye surgery or an eye injury, or had a condition that caused inflammation inside the eye.
Be sure to mention your eye floaters to your optometrist, even if you only see a few. Although chances are the floaters aren't a sign of a serious eye condition, your eye doctor will want to take a look at them.
Even harmless floaters can be annoying. A qualitative study published in the Journal of Patient-Reported Outcomes in 2025 noted that floaters can interfere with reading, typing, driving, shopping, crocheting and watching TV. Some study participants also reported fatigue, headaches or eyestrain from floaters.
When Should You Worry About Floaters?
In some cases, floaters could be a sign of a serious eye issue, including:
- A Torn or Detached Retina. A sudden increase in floaters or flashes (bright lights that appear in vision with no apparent source) may happen if you have a torn or detached retina. Emergency treatment to repair and reattach the retina may help you avoid permanent vision loss.
- Vitreous Hemorrhage. Floaters may also be caused by a vitreous hemorrhage (bleeding inside the eye). You may be more likely to develop a vitreous hemorrhage if you have diabetic retinopathy or a torn retina.
- Inflammation or Infection. Floaters can be a sign of an infection inside the eye or uveitis, a potentially dangerous inflammation of the middle eye.
Call your optometrist immediately if you notice any of these symptoms:
- A Sudden Increase in Floaters or Flashes
- A Shadow or Dark Spot in Your Vision (The spot may look as if a dark curtain suddenly fell over your eyes.)
- Sudden Blurriness or Reduced Vision
- A Decrease in Peripheral (Side) Vision
If you can't reach your eye doctor, go to the emergency room.
What Treatment Options Are Available?
Treatment depends on the cause of the floaters. If you have a torn or detached retina, you'll need surgery to repair the retina, if necessary, and reattach it to the eye. Your eye doctor may recommend replacing the vitreous with a saline solution or an air or gas bubble during a surgical procedure called a vitrectomy. Replacing the vitreous removes floaters and blood that interfere with vision. A vitrectomy may also be needed to help repair a detached retina.
Antibiotics and antifungals may be needed to treat infections. If inflammation is the cause of your floaters, your eye doctor may prescribe corticosteroid eye drops or injections to reduce inflammation or immunosuppressants or medications to treat spasms.
