Eye pain can be caused by inflammatory diseases, visual fatigue, allergies and other factors. 1. Inflammatory diseases: conjunctivitis, keratitis, blepharitis (also known as granuloma) and other local inflammatory diseases can cause mucosal congestion and edema, triggering the expansion of submucosal capillaries, resulting in pain when pressed. 2. Visual fatigue: staying up late, poor sleep quality, excessive eye use and other bad habits can trigger visual fatigue, resulting in local ciliary muscle spasm, blepharoplasty secretion dysfunction. This leads to symptoms such as reduced lubrication of the eye surface, dryness and pressure pain in the eyes. 3. Allergy: patients with allergies triggered by contact with allergens may show allergic reactions such as eye swelling and pressure pain. Common allergens include dust mites, pollen, willow floss, etc. If the allergens are not clear, you can go to a regular medical institution for allergen testing. Other causes of eye pain can be seen, patients should consult a doctor in a timely manner, under the diagnosis and guidance of a professional doctor for treatment.
