Green mucus in your eye is often a sign of a bacterial infection, which causes your body to produce extra discharge to fight off the germs.
When you see green mucus coming from your eye, it usually means that an infection might be present. Bacterial infections, such as bacterial conjunctivitis, can make the eye produce extra mucus that turns green. This green color happens because your body is fighting the bacteria by sending white blood cells to the area. These cells mix with the mucus, giving it a greenish tint. You might also notice other symptoms like redness, itchiness, or the eye feeling sore. It’s important to remember that green mucus is not just a normal reaction to dust or allergies; it is more often a signal that your eye needs treatment, like antibiotic eye drops. If you have green mucus along with discomfort or changes in your vision, it’s a good idea to see an eye doctor. They can help you figure out if there is a bacterial infection and give you the right medicine so your eye can heal properly.
