Preventing Conjunctivitis

Infectious conjunctivitis is highly contagious. Someone with infectious conjunctivitis is usually contagious for seven to 14 days after symptoms first appear. During this period, those with conjunctivitis and the people around them should wash their hands frequently and keep their fingers away from their eyes. The patient's clothes and bedding should also be washed frequently.

Noninfectious conjunctivitis has many causes. You may be able to avoid conjunctivitis by avoiding allergens (substances you are allergic to) and making sure your contact lenses fit properly.
