For conjunctivitis (pink eye), keep your eyes clean, avoid touching or rubbing them, and wash your hands frequently to prevent the spread. You can use lubricating (artificial tear) drops, if it?s allergic, antihistamine drops and if bacterial (with thick discharge), antibiotic drops.... If symptoms worsen, vision is affected, or they don?t improve within 2?3 days, consult an eye doctor for proper treatment..
