Pink eye has different causes. If it is caused by bacterial conjunctivitis, you should use antibiotic eye drops or ointments to relieve it. Several days later you will feel much better. If it is caused by Viral conjunctivitis, then there will be no treatment. The virus will have to run its course for two to three weeks. However, cool or warm compresses can help a little.If you have Allergic conjunctivitis, you'd better figure out the allergic trigger and avoid it. You can also use the anti-allergy medications. Therefore, to prevent pink eye, you should wash your hands often and don't touch your eye. Change your pillowcases and your towels often and do not share them with other people.
