A red eye is usually nothing to worry about and often gets better on its own. But sometimes it can be more serious and you'll need to get medical help.
Common causes of a red eye
Lots of different things can cause a red eye.
Your symptoms might give you an idea of what's causing it.
What to do if you have a red eye
If your eye does not hurt and your sight is not affected, it's probably nothing serious. It may get better on its own in a few days.
Until it has got better:
- try not to touch or rub your eye
- do not wear contact lenses
You can ask a pharmacist if:
- there's anything you can do to treat your eye yourself
- you can buy anything to help, such as cleaning solutions or eyedrops
- you need to see a GP
