Preventing floaters

NHS ChoicesMedical Reference

NHS Choices Logo

As floaters are part of the natural ageing process, you cannot prevent them from occurring.

However, it is important that you are aware of the signs of retinal detachment, so that you can seek an early diagnosis and treatment to protect your sight.

See your optometrist (optician) if:

  • you suddenly start to see floaters and white flashes, having never seen them before
  • you notice a sudden increase in the number of floaters, or flashes
  • you notice a grey area that appears in your outer vision
  • you have had floaters, or flashes, for a while but they are now starting to look different
  • you are finding it difficult to carry out day-to-day tasks, such as reading and driving
  • you have had floaters, or flashes, in one eye for some time and they are now starting to affect your other eye
