What causes eye pain?

Eye pain may be a symptom of various eye problems. Common causes include: 1. Eye strain: Prolonged viewing of electronic screens, reading, or working can lead to tension in the eye muscles. 2. Dry eye: Insufficient tear secretion causing inadequate lubrication of the eye surface, resulting in a stabbing or burning sensation. 3. Conjunctivitis: Eye redness and inflammation caused by bacterial, viral infection, or allergic reaction. 4. Scleritis: Inflammation of the outer layer of the eyeball, often accompanied by blurred vision and severe eye pain. 5. Meibomitis: Blockage of the meibomian glands at the base of the eyelashes, which can cause eyelid redness, swelling, and pain. 6. Glaucoma: Increased intraocular pressure compressing the optic nerve, accompanied by eye pain, headache, and vision loss. Please note, if the pain persists or worsens, it is essential to seek timely medical attention to avoid delayed treatment.
