Eye pain is a symptom, not a disease. Therefore, treatment varies depending on the disease causing the eye pain. First, the most common diseases include visual fatigue. Swelling and pain in both eyeballs caused by binocular vision fatigue requires medication to relieve vision fatigue, such as Sturgeon eye drops. The first is to look less at electronic products such as computers and cell phones. Second, eye pain caused by iritis. In this type of pain, the pressure pain is particularly pronounced and also affects vision. Such patients should have their pupils dilated immediately and be treated with hormonal eye drops and oral hormones. Third, eye pain caused by glaucoma. Eye pain caused by glaucoma is mainly hypertensive and distending pain, accompanied by nausea and headache. Such patients should immediately go to the hospital for IOP lowering and clear diagnostic treatment.
