What causes eye pain?

Eye pain can be caused by various factors. The following are some common causes: 1. Eye strain: Prolonged use of electronic devices such as computers and mobile phones may lead to dryness, fatigue, and subsequently pain in the eyes. 2. Dry eye syndrome: Insufficient tear production or excessive tear evaporation prevents adequate lubrication of the eye surface, causing a stinging or burning sensation. 3. Conjunctivitis: Inflammation of the conjunctiva caused by bacteria, viruses, or allergens, often accompanied by redness, itching, and pain. 4. Glaucoma: Increased intraocular pressure compresses the optic nerve, causing severe eye pain, which may be accompanied by vision loss, nausea, and vomiting. 5. Vision problems: Uncorrected nearsightedness, farsightedness, or astigmatism can cause discomfort due to the eyes straining to focus. 6. Eye injuries: Such as corneal scratches or foreign bodies entering the eye, may cause pain and sensitivity. 7. Intraocular diseases: Conditions such as uveitis or eye tumors may also cause eye pain. Note: If you experience persistent eye pain, seek immediate medical attention for proper diagnosis and treatment.
