Red eye is an inflammation of the transparent membrane that lines the eyelid and eyeball. This membrane is called the conjunctiva. When small blood vessels in the conjunctiva become swollen and irritated, they're more visible. This is what causes the whites of the eyes to appear reddish or pink. Pink eye also is called conjunctivitis.
Symptoms
The most common red eye symptoms include:
- Redness in one or both eyes.
- Itchiness in one or both eyes.
- A gritty feeling in one or both eyes.
- A discharge in one or both eyes that forms a crust during the night that may prevent your eye or eyes from opening in the morning.
- Tearing.
- Sensitivity to light, called photophobia.
Preventing the spread of red eye
Practice good hygiene to control the spread of red eye. For instance:
- Don't touch your eyes with your hands.
- Wash your hands often.
- Use a clean towel and washcloth daily.
- Don't share towels or washcloths.
- Change your pillowcases often.
- Throw away old eye cosmetics, such as mascara.
- Don't share eye cosmetics or personal eye care items.
- Keep in mind that red eye is no more contagious than the common cold. It's okay to return to work, school or child care if you're able to practice good hygiene and avoid close contact. However, if work, school or child care involves close contact with others it may be best to stay home until you or your child's symptoms clear up.
