Eye floaters (those little specks, cobwebs, or squiggly lines that drift in your vision) are generally harmless, but can be scary. When you’re supposed to be looking at something, you may notice a flutter or float of particulate matter. Eye floaters occur when the vitreous, a gel-like substance in the eye, shrinks or clots as you get older. Although most floaters are just a nuisance, you should see a doctor if you experience sudden blind spots, a sudden increase in floaters, or other vision changes.
What are Eye Floaters?
Eye floaters are small shadowy spots, wispy threads, or squiggly lines that drift across your vision. They are most visible against bright surfaces, such as the sky or a blank screen. These floaters move with your eyes and dart away when you try to look directly at them. Most floaters are harmless, but if you notice a sudden increase in the floaters in your vision, they could be associated with flashes of light or changes in vision that could be a sign of a problem, and you should see an eye doctor right away.
What Are Eye Floaters Caused By?
Floaters happen because the vitreous, the gel-like substance filling your eye, is starting to change as a natural part of the aging process. As the vitreous gel begins to slowly become more liquid and as microscopic fibers in the gel strands clump together, tiny clusters of gel fibers cast shadows on your retina. Your brain then interprets the drifting spots or squiggles that you see in your vision as the shadows from these tiny clusters of gel.
But sometimes, floaters may be associated with more serious conditions, including:
- Eye infections
- Uveitis (inflammation inside the eye)
- Retinal tears or detachments
Who Is Most at Risk?
Certain people are more susceptible to experiencing floaters. You are at increased risk if you:
- Are nearsighted
- Have had cataract surgery
- Have diabetes, which can result in diabetic retinopathy
- Are aging
Signs to Look Out for
The majority of floaters are benign, but if you notice any of the following symptoms—a sudden spike in floaters, light flashes, or a dark shadow in your side vision—you should get emergency care because these could indicate a retinal tear or detachment. To avoid vision loss, time is of the essence. If these symptoms develop, consult an eye specialist right away.
How Do Floaters Get Diagnosed?
Special drops enlarge your pupils during a dilated eye exam, allowing the physician to see your retina and vitreous. This makes it easier to identify any troubling alterations, such as retinal tears or other anomalies. The best way to determine whether your floaters are harmless or require treatment is to undergo the quick and painless procedure.
What Constitutes a Medical Emergency with Floaters?
Although the majority of floaters are harmless, some symptoms may point to more serious problems:
- An abrupt rise in frequency
- Light bursts
- A shadow or dark curtain obscuring your vision
These symptoms may indicate a retinal tear or detachment, which calls for prompt medical attention to avoid blindness.
Options for Floater Treatment
Since floaters often become less noticeable over time, no treatment is necessary in many cases. Nonetheless, there are choices for people who notice a noticeable visual impairment:
- Vitrectomy: A surgical technique in which the vitreous gel is removed and replaced with a saline solution.
- Laser Therapy: This procedure breaks up the floaters with lasers, making them less obvious. Since both treatments carry risks, such as infection and retinal damage, they are typically only taken into consideration in extreme circumstances.
Lifestyle Advice for Floaters
Some lifestyle adjustments can help control mild floaters:
- Eye exercises: You can move floaters out of your line of sight by moving your eyes up and down.
- Supplements and diet: Overall eye health can be supported by eating a diet high in zinc, vitamin A, and omega-3 fatty acids.
- Don’t smoke: Smoking can worsen eye conditions and impair eye health in general.
