Conjunctivitis is an inflammation of the conjunctiva. Conjunctiva is a transparent mucous membrane that lines the eyelids and outer eye. It helps to protect the eye-ball and keeps it moist. When this membrane becomes inflamed, the condition is called conjunctivitis. It is a very common condition, but some people seem to be more susceptible to it than others.
Causes: Conjunctivitis can be caused by a number of different agents: infection, allergy, chemical irritants (chlorinated water in a swimming pool, for example, or household cleaning products), or even irritation from eyelashes that have turned inward toward the eye, brushing up against it with every blink.

Symptoms:
1. Blurred vision.
2. False sensation of something in eye.
3. A vague feeling of pain in one eye.
4. Pus may collect in the inner corner of the eye, appearing also as a dried crust in the eye when you awaken.
5. Redness may result from the inflammation of the conjunctiva.
Treatment
If you suffer from any eye problem, get it checked by the doctor. Many of the symptoms of conjunctivitis can also be associated with other conditions, so you should have your eye checked by a doctor--especially as the appropriate treatment for a case of conjunctivitis will depend on the origin of the condition.
1. If the cause is an infection, your doctor will prescribe antibiotic eye-drops. (Occasionally a case will not respond to such eye-drops. If that happens, you must wait for your body's natural defenses to overcome the infection.)
2. If an allergic response is causing the eye to become irritated, the ovious treatment is to remove the allergen. Of course, the allergen may be either unknown or ubiquitous (as pollen is at certain times of the year), and therefore impossible to remove.
