Topic Overview
Not having enough
		tears (dry eye) is caused by a lack of one or more of
		the substances that make up tears.
Dry eyes are common in those
		who wear contact lenses. Eye
		diseases, other diseases, and certain
		medicines can also cause dry eyes.
Symptoms of dry
		eyes include:
- Feeling like there is something in the
		  eye.
- Tearing or burning (or both).
- Dryness in the eye
		  (a hot, sandy feeling).
- Redness.
Symptoms may get worse at the end of the day and in drafty,
		dry, smoky, or dusty environments.
Dry eye may also cause a type
		of keratitis (inflammation of the cornea). Changes in the type of
		contact lens and the way the lens sits on the eye may help correct this
		problem.
Dry eye symptoms can be especially bad in
		people who wear soft contact lenses. Soft lenses absorb water from the eye
		surface and make the eye dry. Dryness may lead to patchy loss of cells in the
		cornea. Trying a different type of lens may help the problem.
