Floaters - Symptoms 

Symptoms of floaters 

If you have floaters, you may not notice them all the time. When your eyes are still, or you are gazing into space, you may see them drift slowly across your vision.

Floaters are usually grey and semi-transparent. They may move when you move your eyes. When you move your eyes to look in different directions, the floaters may appear to move quickly. However, floaters do not tend to follow your eye movement precisely and they will often seem to dart away as you try to look directly at them.

Different forms of floaters

Floaters can occur in a variety of different forms. They may appear as:

  • dots 
  • circles 
  • lines 
  • cobwebs 
  • other shapes

You may notice lots of small floaters in your field of vision or just one or two larger ones. Most floaters are small and quickly move out of your field of vision. Larger floaters can be distracting and make activities that involve high levels of concentration, such as reading or driving, difficult.

Floaters are often most noticeable when you are looking at a clear-coloured background, such as a white wall or a clear sky.

Retinal detachment

In rare cases, floaters may be a sign of retinal detachment (when the retina separates from the wall at the back of the eye). If you have retinal detachment, you will usually have:

  • a large number of floaters
  • bright, flashing lights
  • some loss of vision

If you think that you may have retinal detachment, seek urgent medical attention from your GP or optometrist (optician).
