Red eye


Open all pages about Red eye

Common causes of a red eye include a burst blood vessel, an eye infection, an allergic reaction or dry eyes.

If your eye is red but not painful and does not affect your sight, it will probably get better in a few days if you avoid touching or rubbing it.

A red eye is usually nothing to worry about and often gets better on its own. But sometimes it can be serious and you'll need medical help.
