Eye infections occur when harmful germs, like bacteria or viruses, invade the eye. Common symptoms include redness, swelling, pain, and discharge. Conditions such as conjunctivitis (pink eye) and keratitis can result from these infections, affecting the outer layer of the eye or the cornea. These infections can spread easily, especially in crowded places or through touching the eyes with unwashed hands. It's important to practice good hygiene, like washing hands regularly and avoiding sharing personal items, to prevent eye infections. If symptoms arise, consulting an eye care professional is crucial for proper diagnosis and treatment.
