Home treatments for pink eye
Apply an over-the-counter allergy medicine. An over-the-counter allergy medicine is enough to cure mild allergic conjunctivitis with several days of applications.
Try an antihistamine. When exposed to the allergens, the body produces histamines, chemicals that caused the symptoms of pink eye. And using an antihistamine can reduce the level of histamines, thus ease your symptoms.
Use a decongestant. Unlike the antihistamine, a decongestant is used to ease inflammation, thereby preventing eye tissue from getting further inflammation.
Clean the infected eye regularly. To curb the recurring of bacteria, it is important to clean your eyes when the drainage develops in your eye.
Wash your hands before and after cleaning your eyes.
Start at the inside corner and pass over the entire eye gently to the outside corner of your eye, which will make sure the discharge is safely wiped out from your eye.
Use a clean washcloth for each wipe in case of getting the discharge back to your eye.
Apply a cold or warm compress. Wet a soft and clean cloth with water. Apply it to the infected eye with gentle pressure.
Usually, cold compresses better for allergic conjunctivitis, but for viral or bacterial pink eye, it is preferable to use warm compresses since it can reduce swelling in eye.
Be careful that warm compresses have higher risk of spreading infection between two eyes, so make sure to use a clean compress for each eye.
