Your eyes become red or bloodshot from the blood vessels on the surface of the eyes getting irritated and enlarged. Many factors can contribute to red eyes, including dust or foreign bodies in the eye, allergies and eye injuries. Some eye infections -- including conjunctivitis and blepharitis -- can also cause eye redness, according to MedLinePlus. Most cases of eye redness can easily be treated at home, but if your vision is affected or you are experiencing pain you should seek medical attention.

Wash your hands thoroughly with soap and warm water. When your eyes are red and irritated, you're likely to instinctively touch or rub them. Because of this, it's a good idea to wash your hands frequently throughout the day. This can be especially helpful if you have an eye infection that spreads easily.
Lie down in a comfortable place.
Place cool compresses over your eye or eyes. If the compresses are too cold, try wrapping them in a cloth or towel.
Lay with the compresses over your eyes for between five and 10 minutes.
Repeat these procedures throughout the day when your eyes become irritated or uncomfortable.
