Conjunctivitis is where your eyes are red and sore. It's usually caused by an infection or allergy.
Conjunctivitis usually makes your eyes red, itchy and uncomfortable.
Conjunctivitis usually gets better on its own. Washing your eyelids with clean water can help. You may need antibiotics if it's caused by bacteria.
To avoid spreading conjunctivitis, avoid rubbing your eyes, wash your hands regularly and avoid sharing towels and pillows.
