There are a three broad categories of conjunctivitis: Viral, Bacterial and Allergic.
Viral is often associated with the common cold, the same virus that is associated with a sore throat or runny nose. With this type being a viral infection, antibiotic drops won’t work, but this usually goes away itself like the common cold. (This is the most contagious)
Bacterial will usually contain a lot of pus in the eye, along with redness. Antibiotic eye drops would need to be prescribed, be sure to see your eye doctor.
Allergic conjunctivitis is not contagious and is associated with something the person may be allergic to, such as pet dander, pollen, or something that may be in the environment. Using anti-allergy eye drops would be useful in this case, along with artificial tears. Wash your hands to avoid pink eye.
HOW CAN YOU PREVENT THE PINK EYE ATTACK?
WASH YOUR HANDS. Good hygiene is a necessity all the time, but if you are exposed to anyone with Viral or Bacterial conjunctivitis you’ll want to take extra caution.
1. Keep your hands away from your face and eyes.
2. Do not reuse towels or anything that you use to wipe your face with, launder these regularly.
3. Change out the pillowcases frequently.
4. Do not share eye make-up with others, and keep cosmetic brushes washed.
5. Take proper care of contact lenses especially when taking them in and out of your eyes, and follow the directions.
Usually your Optometrist can diagnose conjunctivitis, and he/she will determine the proper care for you. If any form of pink eye lasts longer than a few days, you will want to see an Ophthalmologist to rule out any serious eye problems that could lead to blindness.
