Do the whites of your eyes have more red lines than a road map? If so, here's what you can do.
Water your eyes. "It seems obvious, but if your red eyes are a result of not getting enough sleep, find a way to catch up on your rest," says Mitchell Friedlaender, M.D., a California ophthalmologist and director of corneal and external diseases in the Division of Ophthalmology at Scripps Clinic and Research Foundation in LaJolla, California. "Closing your eyes for 7 to 8 hours helps to rehydrate them. Without sleep the eyes can dry out. And dry eyes are red eyes."
Treat your eyelids. If your eyes are red when you wake up, the problem may not be in your eyes but on your eyelids. "It's called blepharitis, and it's a low-grade infection of your eyelids," says Dr. Friedlaender. "You can treat it by washing your eyelids with warm water at night before you go to bed. Make sure you cleanse the lids so that the debris, oils, bacteria, makeup, and dandruff on the lashes are all removed."

Use drops sparingly. "Drops designed to get the red out have an agent in them that works to constrict your blood vessels," says Dr. Friedlaender. "They take the redness out by shrinking the blood vessels in your eye, which makes your eye look whiter for the time being.

"The problem is, most of those drops have a rebound effect so that when they wear off in a couple of hours, the redness comes back worse than it was in the first place."
The best advice: Use eyedrops sparingly.
Shed crocodile tears. Do you arrive at work bright-eyed, but leave in the red? "Redness that comes on during the day is caused by dryness," says Dr. Friedlaender. "If that's the case, over-the-counter artificial tears can be used to moisten the eyes." Unlike other eyedrops, artificial tears do not shrink blood vessels.
Get your eyes to cool it. "Use a cool, wet washcloth and lay it over your closed eyes," says Dr. Friedlaender. "The cold will constrict the blood vessels without the rebound effect, plus the water will add moisture to your eyes."
