What are floaters and flashes?
Floaters appear as dark particles or cobweb-like shapes that drift across your vision. They are due to changes in the jelly-like area of the eye and usually require no treatment, often fading over time.
As the eye ages, the vitreous body shrinks and may separate from the retina — a process called posterior vitreous detachment (PVD). This can produce a sudden burst of floaters alongside flashes of light.
When to seek help urgently
PVD is usually harmless, but it can occasionally tear the retina, which may lead to a retinal detachment. The critical symptom to watch for is a dark or black “curtain” coming over your vision.
See an eye specialist promptly if you notice new floaters, flashing lights, or a shadow or curtain across your vision. Call us any time on 0800 750 750.
