Eye floaters are caused by moving particles that float in the vitreous humour – the gel-like fluid in the centre of the eye. They appear in your field of vision in all sorts of shapes and sizes: long strands, large spots or smaller dots. In most cases it’s normal and completely harmless. To understand more, let’s look in more detail at what causes eye floaters and spots.
In the middle of the eyeball is a fluid with the consistency of jelly. This is called the vitreous humour. As we age, the consistency of the vitreous humour changes and becomes more watery, as small particles of the gel break off and dissolve. Some of these small pieces remain undissolved and cast shadows on the retina as they drift around. The shadows are what we see when we experience eye floaters.
While most people will experience these at some time, others are more susceptible:
Probably not. The breaking down of the vitreous humour is normal and it is extremely common to experience floaters now and then, although our brains do become good at filtering them out most of the time so that we can concentrate on what we really want to look at.
Sometimes there will be a condition, injury or infection that is causing the eye floaters. Underlying conditions that can cause floaters include short-sightedness and diabetes.
Changes in the frequency or size of your floaters could indicate that something more serious is going on. Here are some indicators that you should seek immediate medical attention from an eye specialist:
These symptoms could indicate a detached retina or another serious vision problem that requires attention.
For most people, eye floaters are at worst a minor distraction, so treatment is not needed. If yours are causing problems and you wish they would disappear, treatment options may be available to you:
