Introduction
If the inflammatory response in conjunctivitis is severe—for example, bacterial conjunctivitis accompanied by significant conjunctival hyperemia and edema, or viral conjunctivitis causing conjunctival ulcers—the inflammatory irritation can lead to a stabbing or aching sensation in the eye. Pain may worsen particularly during blinking, and may be accompanied by increased secretions, photophobia, and other symptoms. In such cases, the pain is more pronounced.
Generally, some types of conjunctivitis can cause eye pain, while others mainly present with foreign body sensation and itching, with little or no noticeable pain. The specific symptoms depend on the type and severity of the inflammation. If in doubt, it is advisable to seek medical consultation promptly. Detailed analysis is as follows:
When the inflammatory response in conjunctivitis is severe—such as in bacterial conjunctivitis with significant conjunctival congestion and edema, or viral conjunctivitis leading to conjunctival ulcers—the inflammation may stimulate sharp or aching pain in the eye. Pain may worsen during blinking and is often accompanied by increased discharge, photophobia, and other symptoms. In such cases, pain is more prominent.
In mild allergic conjunctivitis or early-stage viral conjunctivitis, inflammation primarily stimulates surface ocular nerves, causing itching and a foreign body sensation. Pain is relatively mild and may only manifest as occasional slight discomfort, which can easily be overlooked. However, as the condition progresses and corneal damage develops, noticeable pain may gradually appear.
When symptoms of conjunctivitis occur, avoid rubbing the eyes to prevent corneal injury and worsening pain; reduce exposure to bright light and avoid prolonged screen use; seek timely medical evaluation to determine the type of inflammation, and follow medical advice for treatment to prevent disease progression and protect eye health.
