Eye Floaters and Flashes
Hindi / common name: Eye Floaters (aankhon ke aage machhar, dhaage ya dhabbe udna)
Floaters are small specks, dots, threads or cobweb-like shapes that drift across your vision, especially when looking at a bright sky or white wall. Most floaters are harmless and come from natural changes in the gel (vitreous) that fills the eye. However, a sudden increase in floaters, especially with flashes of light or a shadow, can be a warning sign of a retinal tear or detachment and needs urgent examination.
Symptoms of Eye Floaters
- Dots, threads, rings or cobwebs that move when your eyes move
- Floaters most visible against bright backgrounds
- A new large floater, often ring-shaped, when the vitreous separates from the retina
- Flashes of light, like lightning streaks, at the edge of vision
- Sometimes a shadow or curtain in part of the vision (warning sign)
Causes and risk factors
- Age-related liquefaction of the vitreous gel, very common after 50
- Posterior vitreous detachment (PVD), when the gel separates from the retina
- Myopia, especially high myopia, which makes floaters start earlier
- Eye surgery such as cataract surgery
- Eye injury
- Bleeding inside the eye, for example from diabetic retinopathy, or inflammation (uveitis)
How it is diagnosed
An ophthalmologist examines the retina carefully after dilating the pupils to check for any tear, detachment, bleeding or inflammation. Ultrasound or OCT may be used. Anyone with sudden new floaters or flashes should have this examination as soon as possible, ideally the same day.
Treatment options
- Most floaters need no treatment and become less noticeable over months as the brain adapts
- Retinal tears are treated with laser or freezing treatment to prevent detachment
- Retinal detachment needs urgent surgery
- Rarely, very troublesome floaters may be treated with YAG laser or vitrectomy surgery, after careful discussion of risks with a specialist
Glasses and lens options
Glasses do not remove floaters. Correct power, anti-glare lenses and sunglasses in bright light can make floaters less bothersome.
Prevention and everyday care
- Most floaters cannot be prevented
- Know the warning signs and act fast if they appear
- People with high myopia or diabetes should have regular dilated eye checks
- Wear protective eyewear during sports and work that risks eye injury
When to see an eye specialist the same day
- A sudden shower of new floaters
- Flashes of light, especially new ones
- A dark curtain or shadow over part of your vision
- Sudden loss of vision
- Floaters after an eye injury

Are eye floaters dangerous?
Most long-standing floaters are harmless. Sudden new floaters, especially with flashes or a shadow, can mean a retinal tear and need urgent examination.
Will floaters go away?
They usually do not disappear completely, but most become much less noticeable as the brain learns to ignore them.
Why do I see floaters more on bright days?
Bright backgrounds like the sky make the shadows of floaters on the retina easier to see.
Can eye drops remove floaters?
No eye drops are proven to dissolve floaters.
Are floaters more common with myopia?
Yes. People with myopia, especially high myopia, tend to develop floaters earlier and have a higher risk of retinal tears.
