Quick answer
What is Eye floaters?
Floaters are small shapes — dots, threads, cobwebs or squiggles — that drift across your field of vision, often more noticeable against a bright, plain background like the sky or a white wall. They are caused by tiny clumps or strands within the jelly-like substance (vitreous) that fills the eye, which cast shadows on the retina.
- How it is treated: Most floaters need no treatment, and the main role of assessment is to distinguish harmless floaters from the warning signs of a retinal problem.
- Self-care: There is no way to prevent most floaters, and harmless ones usually need no action beyond reassurance.
- When to seek help: Seek urgent eye assessment (eye casualty or A&E) for a sudden increase in floaters, flashes of light, or a dark shadow or curtain across your vision — these can signal a retinal tear or detachment.
What it is
Floaters are small shapes — dots, threads, cobwebs or squiggles — that drift across your field of vision, often more noticeable against a bright, plain background like the sky or a white wall. They are caused by tiny clumps or strands within the jelly-like substance (vitreous) that fills the eye, which cast shadows on the retina. Most floaters are harmless and very common, becoming more frequent with age as the vitreous naturally changes, and people often learn to ignore them. However, a sudden increase in floaters, especially if accompanied by flashes of light or a dark shadow or "curtain" across the vision, can be a warning sign of a retinal tear or detachment — a sight-threatening emergency — so these particular symptoms need urgent assessment.
How it is treated
Most floaters need no treatment, and the main role of assessment is to distinguish harmless floaters from the warning signs of a retinal problem. Long-standing, stable floaters are generally left alone, and people usually adjust to them over time. New floaters, particularly with flashes of light or a shadow across the vision, are checked urgently by an eye specialist to look for a retinal tear or detachment, which can often be treated (for example with laser or surgery) if caught early. In the small number of cases where harmless floaters are severe and persistently affect vision and quality of life, specialist treatments may occasionally be considered, but this is uncommon. The key practical message is knowing which symptoms need urgent attention.

Beyond medication
Lifestyle and self-care
There is no way to prevent most floaters, and harmless ones usually need no action beyond reassurance. Knowing the warning signs (a sudden increase, flashes, or a shadow across vision) and seeking urgent help if they occur is the important step.
When to get help
When to see a doctor
Seek urgent eye assessment (eye casualty or A&E) for a sudden increase in floaters, flashes of light, or a dark shadow or curtain across your vision — these can signal a retinal tear or detachment. Long-standing, unchanged floaters are usually harmless.

Answers
Eye floaters: frequently asked questions
Are eye floaters serious?
Most floaters are harmless and part of the eye's natural ageing. However, a sudden increase, especially with flashes of light or a shadow across the vision, can signal a retinal tear or detachment and needs urgent assessment.
Can floaters be treated?
Harmless floaters usually need no treatment and people often adjust to them. If floaters signal a retinal problem, that is treated urgently. Rarely, specialist treatment is considered for severe, persistent floaters.
