    There are actually three common types of pink eye (红眼病), medically known as conjunctivitis (结膜炎). Two-viral and bacterial-can spread from person to person. The third, allergic, involves your surrounding environment.

How does pink eye start? An infected person touches his or her eyes, then touches something else. If you touch that person or object and then your eyes, you can contract the same infection. That includes shaking hands, sharing towels or pillows, or even papers if you work in an office job. So when it comes to how to get pink eye, not washing your hands-and frequently touching your face-can both play a big role. Pink eye can also spread when you use old makeup or share makeup. In fact, if someone in your household develops bacterial or viral conjunctivitis, replace or at least wash everything you can, including sheets, towels, taps, and other bathroom equipment.

Contact lens (隐形眼镜) is another common way to develop bacterial conjunctivitis. Always wash and dry your hands before handling your contacts. Use the solution and storage methods recommended by your eye doctor. All these steps become even more important if someone in your household already has pink eye. If you do develop conjunctivitis yourself, take your contacts out and throw them away. Wear glasses until your doctor gives you the OK to put your lenses back in. And clean your glasses frequently too. When it’s time to wear contacts again, start with a new pair.

Unlike bacterial and viral conjunctivitis, allergic conjunctivitis is caused by something in your surrounding environment. You might develop symptoms during allergy season in the spring or fall, caused by the same flowers or trees that cause hay fever. This adds the difficulties to the prevention of conjunctivitis.

While not every case of pink eye requires medical treatment, doctor recommends that anyone with a sudden start of these symptoms see a doctor. Some cases can turn serious, and symptoms can be similar to those of other vision-threatening eye conditions
