It can affect people of all ages and spreads easily, especially in schools and workplaces. The good news is that most cases are mild and treatable at home with simple remedies and good hygiene.
Bottom line: Identify the type, treat symptoms, and prevent spread – most pink eye cases clear quickly with proper care.

Pink eye happens when the conjunctiva – the clear tissue lining your eyelids and covering the white part of your eye – becomes inflamed. This inflammation can be caused by viruses, bacteria, or allergens. Although it usually isn’t serious, it can be very contagious, so early treatment and prevention are key.
Recognizing pink eye early helps prevent spreading it and speeds up treatment. In fact, here are the most common symptoms:
There are three main types of conjunctivitis. Furthermore, each one has different causes and slightly different symptoms. Because of this, use the chart below to help identify which type you may have:
| Type of Conjunctivitis | Key Symptoms | Typical Causes |
|---|---|---|
| Viral Conjunctivitis | Watery discharge, red eyes, light sensitivity | Cold, flu, or other respiratory viruses |
| Bacterial Conjunctivitis | Thick yellow or green discharge, eyelid swelling | Bacteria like Staphylococcus or Streptococcus |
| Allergic Conjunctivitis | Itchy, watery eyes; sneezing; puffiness | Pollen, dust mites, pet dander, mold |
Understanding the type of pink eye you’re dealing with will help guide the most effective treatment, which we’ll cover next.
