Almost everyone has floaters. In a large survey of smartphone users, roughly 76% of people under 23 already reported seeing them, and the rate held steady across older age groups at around 73–78%. Floaters are not a sign that something is wrong with your eyes. They are a normal part of how the gel inside your eye ages and changes over time.
Why Floaters Are So Common
Your eye is filled with a clear, jelly-like substance called the vitreous. In young eyes, the proteins and water molecules in this gel are distributed evenly, keeping everything transparent. But as you age, the gel gradually breaks down. Water molecules shift around, creating small pockets of liquid, while protein fibers clump together into tiny strands or specks. These clumps cast shadows on your retina, and those shadows are what you see drifting across your vision.
This process starts earlier than most people expect. About 20% of the vitreous is already liquefied by age 18. By age 80 to 90, roughly half of it has broken down. That’s why floaters tend to become more numerous and noticeable as you get older, even though most younger adults already have at least a few.
What Makes Some People Notice Them More
Not everyone is equally bothered by their floaters. Two people can have a similar number of tiny protein clumps in their vitreous, but one barely notices while the other finds them distracting. Lighting plays a big role: floaters are most visible against bright, uniform backgrounds like a blue sky, a white wall, or a computer screen. People who spend long hours looking at screens or reading may simply have more opportunities to notice them.
Nearsightedness (myopia) is one factor that can increase floater severity. People with higher prescriptions tend to have longer eyeballs, which stretches the vitreous and may accelerate the breakdown process. Eye surgery and eye inflammation can also contribute to floaters appearing earlier or in greater numbers.
Your Brain Learns to Tune Them Out
If you’ve noticed a new floater and then found it less bothersome weeks later, that’s not your imagination. Your brain actively filters out stable visual noise through a process called neuroadaptation. For most people, this adjustment takes about 3 to 6 months. After that period, the floaters are still physically there, but your visual system largely ignores them the same way you stop noticing a watch on your wrist.
This is why eye specialists generally recommend waiting at least six months before considering any treatment. The majority of people adapt well enough that floaters stop affecting their daily life. A smaller group, however, remains persistently bothered. For these individuals, the floaters may be larger, more centrally located, or denser, making them harder for the brain to suppress.
When Floaters Signal Something Serious
A few scattered floaters that drift slowly when you move your eyes are completely normal. What is not normal is a sudden shower of new floaters, especially if accompanied by flashes of light or a shadow creeping across part of your vision. These symptoms can signal a posterior vitreous detachment (PVD), which is when the gel pulls away from the retina entirely.
PVD itself is common with age. It occurs in about 24% of people in their 50s and up to 87% of people in their 80s. Most of the time it resolves without lasting harm. But in about 14.5% of people who develop PVD symptoms, the pulling creates a retinal tear, and roughly 23% experience bleeding inside the eye. A retinal tear left untreated can progress to a retinal detachment, which is a genuine emergency that can cause permanent vision loss. If you experience a sudden burst of new floaters, get your eyes examined the same day if possible.
Floaters From Other Conditions
Age-related collagen clumping is by far the most common cause, but floaters can also appear when blood leaks into the vitreous. This happens in advanced diabetic retinopathy, where damaged blood vessels in the retina become fragile and grow abnormal new branches. These weak vessels can leak small amounts of blood into the vitreous, producing dark spots or strings that look like typical floaters but have a very different cause. People with diabetes who notice new floaters should have their eyes evaluated promptly, since the underlying blood vessel damage may need treatment to prevent vision loss.
Treatment Options and Their Limits
Most floaters don’t require treatment. For people who remain significantly affected after the neuroadaptation window, two options exist: laser treatment and surgery.
Laser vitreolysis uses a focused laser beam to break up large floater clumps inside the eye. In one recent study of 130 patients, 60% reported marked improvement and about 25% reported partial improvement at three months. That sounds promising, but the complication rate was notable: nearly 54% of patients experienced some form of complication, including elevated eye pressure, retinal injury, bleeding inside the eye, or inflammation. Most of these complications were manageable, but the numbers illustrate why this procedure is reserved for cases where floaters genuinely impair quality of life rather than offered as a routine fix.
Vitrectomy, a surgical procedure that removes the vitreous gel entirely and replaces it with a salt solution, is highly effective at eliminating floaters. But it carries the risks of any eye surgery, including cataract formation and, rarely, retinal detachment. It’s considered a last resort for the most severely affected patients.
For the vast majority of people, floaters are simply part of having eyes. They’re distracting at first, your brain learns to work around them, and they fade into the background of everyday vision.
