What causes eye floaters, how do they appear, and when should you seek professional care?
Spots in Your Eyes
Lucy, in her 50s, begins telling her friends that she keeps seeing spots drifting across her vision. Mark quickly responds that he has them too, and eventually got used to them. Margaret says hers went away over time. As her friends casually downplay the symptoms, Lucy can’t shake the feeling that her situation is different.
A visit to an ophthalmologist confirms it. He refers her to a retinologist, where she learns she has a detached vitreous membrane. There’s no immediate treatment. Instead, the specialist explains that her floaters may eventually drift downward—settling out of view—and schedules periodic follow-ups to track the changes.
But Lucy’s symptoms persist. She sees large cobweb-like shadows, especially against bright backgrounds. When she looks up at the blue sky, tiny white flashes, translucent bubbles, and black specks fill the open field of view.
Treatments for Floaters
Margaret tells her that lutein—a natural pigmented antioxidant found in leafy greens like kale and spinach—helped her symptoms. Lutein filters blue light and may protect against macular degeneration or delay cataracts. Some people online even claim it reduces floaters. [1]
Curious, Lucy asks her retinologist. He acknowledges the research but gently resets expectations: it won’t hurt, but it probably won’t help her particular condition.
Then he offers a comparison:
“If you had chest pain, and someone said they needed a triple bypass for the same thing, would that be the treatment you’d want to try?”
Lucy shakes her head. “Of course not.”
“If a friend’s foot pain was solved by wearing a bigger shoe, but your foot had wounds that wouldn’t heal, would you buy larger shoes?”
“No… I’d need to see a specialist.”
“Exactly. A podiatrist might diagnose a diabetic foot. The point is: people may experience ‘floaters,’ but not all floaters have the same cause.”
Lucy nods. “I thought mine was from the membrane detachment.”
“It is. But your friends may have more common floaters—the kind that develop when the gel-like vitreous humor naturally ages and clumps. These cast shadows on the retina. Floaters can also come from inflammation, eye surgery, diabetic retinopathy, or even bleeding in the eye. A sudden increase in floaters or flashes can signal a retinal tear or detachment, which requires immediate attention.” [2,3]
What Are Lucy’s Options?
Lucy sighs. “So what’s the solution for my problem? I keep seeing specks, bubbles, white flashes, and sheets.”
The specialist explains that doctors often prefer to monitor floaters for many months—or even years—before recommending surgery, because most patients adapt over time.
“It has been more than a year,” Lucy stresses. “And they aren’t getting better.”
“For a few large floaters, some patients qualify for laser vitreolysis, a procedure that breaks the floaters apart. But in your case, you’re likely a candidate for a vitrectomy—sometimes called a floaterectomy.” [4]
Lucy’s eyes widen. “It sounds like you’re going to remove my eyes!”
He smiles. “Nothing that dramatic. We remove the vitreous fluid containing the debris and replace it with a clear saline solution.”
“You make it sound simple now.”

FAQ: Questions about eye floaters treatment
What are eye floaters?
Eye floaters are tiny shadows that drift across your vision. They may appear as specks, cobwebs, bubbles, threads, or translucent sheets caused by changes in the vitreous gel inside the eye.
Are eye floaters normal?
Yes. Many people develop floaters naturally as the vitreous humor ages and clumps. However, a sudden increase, new flashes of light, or a curtain-like shadow may signal a retinal tear or detachment and require immediate medical care.
What causes different types of floaters?
Floaters can be caused by vitreous clumping, posterior vitreous detachment, inflammation, eye injury, diabetic retinopathy, bleeding, or post-surgical changes. Each source creates different floater shapes and behaviors.
Can lutein or supplements reduce floaters?
Lutein supports eye health and may protect against macular degeneration, but it has not been proven to eliminate floaters. Its benefits depend on the underlying cause.
What treatments are available for eye floaters?
Most floaters improve or become less noticeable over time. For persistent or severe cases, treatment options include laser vitreolysis or vitrectomy, depending on the floater size, cause, and patient symptoms.
When should I see a doctor about floaters?
Seek immediate attention if floaters suddenly increase, if you see flashes of light, or if part of your vision darkens. These may indicate a retinal tear or detachment.
