What are floaters?

Floaters are very common and many people have them. They're harmless, floating clumps of cells that form in your vitreous as it becomes more watery. You can see them because they cast shadows on your retina when light comes into your eye.

Floaters can be different shapes and sizes and can look like flies, threads, circles, clouds or cobwebs. You may notice that your floaters move around a lot or they may hardly seem to move. They may also become more obvious on sunny days, when looking at a bright screen such as a computer or when looking at a light coloured background.

The number of floaters you have can vary from just the odd one to quite a few. Floaters can be quite frustrating, however most people find that they become less obvious over time as the brain learns to ignore them.


Although most floaters are harmless if you suddenly start to see them or see an increase/changes in the ones you already have you should have your eyes examined by an optometrist as soon as possible.
