However, if you have bacterial pink eye, your doctor may give you an antibiotic in the form of ointment or eye drops. If your eye inflammation is the result of allergies, allergy medicine or eye drops may help get rid of it.\nThe most important thing to remember is that both viral and bacterial pink eye are highly contagious. Pink eye can spread from one eye to the other, and it can easily spread between children and adults if a healthy person comes into contact with fluid from an infected person\u2019s eye. It is most often spread by hand-to-eye-to-hand contact.\nPreventing Pink Eye\n\nDO remove and throw away contact lenses immediately after symptoms start, and clean or change your contact case.\nDO wash your hands often and avoid touching your eyes and face.\nDON\u2019T share towels, wash cloths, or pillows with anyone else while you have pink eye.\nDON\u2019T wear eye makeup until the condition clears, and don\u2019t share makeup with others.\nDO use any medication your doctor prescribes for as long as you\u2019re told, even if symptoms start to clear up.\nDO stay home from work\/school until after the contagious period passes (two to three days).\n\nYou can apply a damp warm or cool washcloth on your eye to sooth irritation, but be careful not to spread the disease to your other eye.\nCan Pink Eye Become Something Worse?\nMost of the time, pink eye clears up quickly on its own or with medication. However, if it is left untreated and gets worse, it could permanently damage the eye.\nPink eye may also be more of a concern if you wear contact lenses, have an immune system deficiency, or have other medical concerns. It can also be a sign of a more serious medical condition if you experience any of the following:\n\nEye pain\nSensitivity to light\nExtreme redness\/irritation\nSymptoms that last longer than a few days or worsen over time\n\nCall your doctor if you experience any of these or have concerns about your pink eye.
