Pink eye or conjunctivitis (sometimes also known as red eye or sore eyes) is basically inflammation of the conjunctiva. The conjunctiva is a thin, clear membrane that forms the outermost layer of the eye and the inside lining of the eyelids. Most often, conjunctivitis develops when this membrane is attacked by a bacterial infection. However, it can also be caused by other factors, such as a viral infection, an irritant such as chlorine in a swimming, or an allergic reaction to some substance. If you are sure that your case of pink eye is the result of an allergic reaction, then you can manage quite well with some home remedies to obtain relief from the itching and burning. If not however, it is better that you visit a doctor. Pink eye usually disappears on its own after a few days, but if it is the result of a bacterial or viral infection, it is better to be on the safe side and have a doctor treat you. The eyes are extremely delicate and pretty much essential, and it is best not to take any risks with them. If conjunctivitis is due to some chemicals, then it is absolutely essential to get medical treatment.
Even if you have allergic conjunctivitis, if the case is very severe you may need antihistamines and other medication, which only a doctor will be able to prescribe. However, for a minor case of pink eye due to an allergy, the best and probably the only treatment needed is a cold compress. You can simply dip two balls of cotton in cool water, lie down, and place a wad of cotton over each eye. You can do this several times during the day for five to ten minutes each time. If you want, you can also use artificial tears, which are easily available over the counter.
