What makes pink eye contagious

If a virus is causing conjunctivitis, antibiotic drops will not help. The eye infection will get better on its own as the body fights off the virus. If you have allergic conjunctivitis, your doctor may prescribe anti-allergy eyedrops or medicine in pill form. Because infectious conjunctivitis is highly contagious, wash your hands after interacting with anyone who has the infection.

Don't share potentially infected items like washcloths, towels, gauze, or cotton balls. This can be difficult among family members, so just do the best you can. If you have pinkeye, it's important to wash your hands often, especially after touching your eyes. The infection can easily spread from one eye to the other on contaminated hands or tissues.

It's also wise not to share cosmetics, especially eye makeup. Bacteria can hang out on beauty products, so avoid using the testers at makeup counters directly on your eyes. And if you've already had a bout of pinkeye, throw away all your eye makeup and splurge on new stuff but don't start using your new products until the infection is completely gone. If you wear contact lenses and you have pinkeye, your doctor or eye doctor may recommend that you not wear contact lenses while infected.

After the infection is gone, clean your lenses carefully. Be sure to disinfect the lenses and case at least twice before wearing them again.

Wearing contact lenses that aren't cleaned properly or aren't your own can cause bacterial conjunctivitis. Both types are very contagious. They are spread through direct or indirect contact with the liquid that drains from the eye of someone who's infected.

One or both eyes may be affected. Allergic conjunctivitis affects both eyes and is a response to an allergy-causing substance such as pollen. In response to allergens, your body produces an antibody called immunoglobulin E IgE. This antibody triggers special cells called mast cells in the mucous lining of your eyes and airways to release inflammatory substances, including histamines.

Your body's release of histamine can produce a number of allergy signs and symptoms, including red or pink eyes.

If you have allergic conjunctivitis, you may experience intense itching, tearing and inflammation of the eyes — as well as sneezing and watery nasal discharge.

Most allergic conjunctivitis can be controlled with allergy eyedrops. Irritation from a chemical splash or foreign object in your eye is also associated with conjunctivitis.

Sometimes flushing and cleaning the eye to rid it of the chemical or object causes redness and irritation. Signs and symptoms, which may include watery eyes and a mucous discharge, usually clear up on their own within about a day. If initial flushing doesn't resolve the symptoms, or if the chemical is a caustic one such as lye, you need to be seen by your doctor or eye specialist as soon as possible. A chemical splash into the eye can cause permanent eye damage.

Persistent symptoms could also indicate that you still have the foreign body in your eye — or possibly a scratch over the cornea or the covering of the eyeball sclera. In both children and adults, pink eye can cause inflammation in the cornea that can affect vision. Prompt evaluation and treatment by your doctor for eye pain, a feeling that something is stuck in your eye foreign body sensation , blurred vision or light sensitivity can reduce the risk of complications.
