In addition to visual fatigue, there are 10 common causes of blurred vision in the clinic and each has its own response.
1. Conjunctivitis. It is also called 'red eye disease' and is often caused by adenovirus. The virus can survive on the surface of the object for about two weeks. Even if it is not cured, it will heal within two weeks. The patient can try cold and heat to relieve itchy swelling, or Use non-prescription eye drops to relieve itching, and anti-viral drugs are available when severe. Often, washing pillowcases and hands can prevent virus transmission.
2. Ocular infection. For herpes simplex keratitis, for example, it is caused by the herpes virus eye infection. Usually eye drops and other drugs will be effective, but the focus is on prevention, wash your hands frequently, do not mess around.
3. Cataract. This is one of the elderly's eye problems, usually without pain and other symptoms, some patients do not even have obvious visual disturbances. If it affects life, you can use artificial crystals to replace the turbid crystals.
4. Glaucoma. The progress of the disease is slow. Vision will gradually be lost for several decades. Regular eye check, once diagnosed, can be treated with drugs, lasers, surgery, etc.
5. Macular degeneration. After age 60, the risk of retinal macular damage is increased. The National Institute of Ophthalmology pointed out that there is no effective therapy for early macular degeneration, and taking certain high-dose vitamins and minerals can delay the late-stage damage. Exercise, maintenance Blood pressure, stable cholesterol, eat green leafy vegetables and fish can reduce the risk of disease.
6. Presbyopia. People above the age of 40 are prone to get this disease. Appropriate reading glasses should be fitted in time to avoid visual fatigue, dry eyes, etc. If myopia is young, consider dual light, tri-optics or progressive lenses.
7. Wear contact lenses to sleep. This is equivalent to providing microorganisms with a 'culture dish' that causes a corneal ulcer and blurred vision. Be sure to remove the lens before going to bed, or change the lens to wear.
8. Diabetes. Patients who have not been diagnosed or whose condition is poorly controlled may develop diabetic retinopathy. Injectable drugs and lasers are available. To control blood sugar, check the eye regularly.
9. High blood sugar. Even without diabetes, long-term high blood sugar can damage the lens and blur vision for hours or days. Obesity or family history of diabetes should be checked regularly for blood sugar.
10. Hypertension. Hypertension patients over the age of 50 to check the eye regularly, high blood pressure can cause the eye 'little stroke', that is, venous thrombosis, mostly unilateral eyes. Often no pain, wake up vision is blurred, although available Thrombolytic medication, but still lose some vision.
