What are Floaters and When Should You Worry?
If you’ve ever noticed small specks, squiggly lines, cobweb-like shadows, or drifting spots in your vision, you’re not alone. These are commonly called floaters, and while they are often harmless, there are times when they can signal a more serious eye condition that may need prompt medical attention.
At Infocus Eye Care, we frequently evaluate patients experiencing new floaters, flashes of light, or sudden changes in vision. Understanding what is normal (and what is not) can help protect your eyesight.
What Exactly Are Floaters?
Floaters are tiny clumps or strands inside the gel-like substance in the eye called the vitreous. As light enters the eye, these small clumps cast shadows on the retina, which is why you see them drifting across your vision.
People often describe floaters as:
Black or gray spots
Squiggly lines
Cobwebs
Transparent circles
Tiny moving shadows
They are usually most noticeable when looking at:
Bright skies
White walls
Computer screens
Light-colored backgrounds
Why Do Floaters Happen?
Floaters become more common with age as the vitreous naturally changes consistency and begins to shrink.
Other risk factors include:
Nearsightedness
Eye injuries
Previous eye surgery
Inflammation inside the eye
Diabetes
Aging changes in the vitreous
In many cases, floaters are simply part of the normal aging process.
When Should You Worry About Floaters?
While many floaters are harmless, a sudden increase in floaters can sometimes indicate a retinal tear or retinal detachment, which can threaten vision if not treated quickly.
You should seek prompt medical evaluation if you notice:
A sudden shower of new floaters
Flashes of light
A dark curtain or shadow in your side vision
Sudden blurry vision
Loss of peripheral vision
These symptoms may indicate that the retina is being pulled or damaged.
What Are Flashes?
Flashes are brief streaks or flickers of light that can happen when the vitreous tugs on the retina. Patients often describe them like:
Lightning streaks
Camera flashes
Flickering lights in peripheral vision
Flashes and floaters together can sometimes be completely benign, but they should still be evaluated to rule out retinal problems.
What Happens During an Evaluation?
A dilated eye exam allows your provider to carefully examine the retina and vitreous for any signs of tears, holes, bleeding, or retinal detachment.
Depending on your symptoms, additional imaging or testing may also be recommended.
Can Floaters Be Treated?
Most floaters become less noticeable over time as the brain gradually adapts to them. In many cases, no treatment is needed.
However, if floaters are severe or significantly affecting vision, treatment options may sometimes be discussed depending on the underlying cause.
Don’t Ignore Sudden Vision Changes
It can be tempting to brush off floaters as “just getting older,” but sudden changes should never be ignored. Early detection of retinal problems can make a major difference in preserving vision.
