Eye Floaters: Causes, Symptoms & When to See an Eye Doctor

Eye floaters are tiny black spots, threads or cobweb-like shapes that drift across your vision. They are common and usually harmless, but a sudden increase in floaters may signal a serious eye problem requiring immediate attention.

What Are Eye Floaters?

Floaters are caused by tiny clumps inside the vitreous gel of the eye. These clumps cast shadows on the retina, making them appear as floating spots that move when your eyes move.

Common Symptoms

  • Black or grey floating spots
  • Cobweb or thread-like shadows
  • Transparent rings or circles
  • Moving dots in your vision
  • Floaters more noticeable against bright backgrounds

Common Causes

  • Age-related vitreous changes
  • Posterior Vitreous Detachment (PVD)
  • High myopia (high minus power)
  • Eye injury
  • Diabetes-related eye disease
  • Retinal tears or retinal detachment

When Should You Worry?

Seek an urgent eye examination if you notice:

  • A sudden increase in floaters
  • Flashes of light
  • A dark curtain over your vision
  • Sudden blurred or reduced vision

These symptoms may indicate a retinal tear or retinal detachment that requires immediate treatment.

Diagnosis & Treatment

A comprehensive dilated eye examination helps determine whether your floaters are harmless or caused by a retinal condition. Most floaters do not need treatment, but serious retinal problems require prompt medical care.

Conclusion

Most eye floaters are a normal part of ageing, but sudden changes should never be ignored. Early diagnosis can protect your vision and prevent permanent sight loss.
