This Week - F : Floaters and Flashes

Dots and lines (floaters) or flashes of light in your vision are common. They're not usually serious.

Check if you have floaters and flashes

Floaters in your vision can look like:

small dark dots
squiggly lines
rings
cobwebs

Flashes look like sudden flashes of light.

They're usually harmless and not a sign of anything serious, especially if:

you've had them for a long time
they're not getting worse
your vision is not affected

Flashes may eventually stop, and floaters often become less noticeable as you get used to them.

Ask for an urgent opticians appointment or get help from NHS 111 if:

you have floaters or flashes in your vision for the first time
you suddenly get floaters or flashes in your vision
the number of floaters or flashes suddenly increases
you have a dark "curtain" or shadow moving across your vision
you also have blurred vision
you also have eye pain
floaters start after eye surgery or an eye injury

These could be signs of a serious problem with the back of your eye, which could permanently affect your vision if it's not treated quickly.

You can call 111 or get help from 111 online.

What happens at your appointment

If you have problems with floaters or flashes in your vision your eyes will be checked at an opticians to see if you need to be seen by an eye doctor (ophthalmologist) for more tests or treatment.

You'll usually only need treatment if you have a problem that could affect your vision.

Causes of floaters and flashes

Lots of people, particularly older people, get floaters and flashes.

They're usually caused by a harmless process called posterior vitreous detachment (PVD), where the gel inside your eyes changes.

Sometimes they can be caused by retinal detachment.

This is serious and can lead to permanent vision loss if not treated.

Floaters and flashes can also happen for no obvious reason.
