Pink eye is a condition known in the medical world as conjunctivitis. The conjunctiva is a clear membrane the covers the eyeball and the inside of the eyelids. When the conjunctiva becomes inflamed or infected, it is called pink eye. Pink eye can be caused by viral or bacterial infections, or allergic reactions to an irritant that has reached the eye. Allergic pink eye is not contagious, but the viral and bacterial pink eyes are extremely contagious and should be treated by a medical professional. There are many signs and symptoms that you should be aware of that may indicate that you have a form of pink eye.
Red or Pink Coloring
Pink eye can cause the conjunctiva or the eyelids to become pink or red. Some cases only cause blood vessels in the sclera, or white part, of the eye to become more red and visible. Other causes make part or all of the sclera in the eye turn very red--appearing to have been bleeding.
Inflammation
It is very common for people to experience inflammation while suffering from pink eye. The inflammation will occur on the upper and lower eyelids and may be very mild ranging to very severe. The inflammation can be so sever that the eye swells partially or totally shut. A cool compress will usually help decrease this inflammation.
Itching
Most cases of pink eye are associated with bothersome itching. Your eyelids may itch, and it may also feel as though your eye itself is itching. This is in large part why this condition is so easily contagious. It is easy to rub your eye without thinking and touch a doorknob or your other eye, causing re-infection or spreading the infection to someone else.
Excessive Tearing
In your body's natural attempt to rid itself of this infection, your eyes will excessively tear. These tears may also be sticky and can cause the eyelids to crust shut during a night's sleep. Gently rubbing the eyes with a cool wet washcloth will wipe away excessive tears and help to open the eyelids after sleeping if they dry shut.
Scratchiness
Although the affected eyes will be producing excess tears to wash away the infection, many people experience a sensation of scratchiness. The eyes may feel as though they are very dry or as if dust or an eyelash has gotten into the eye. It is best to avoid rubbing the eye, because this will only irritate it further and increase the possibility of spreading the infection to your other eye or to another person.
