Myopia in the elderly may be physiological myopia or crystalline myopia caused by cataract. The initial stage of cataract will lead to crystal expansion myopia, patients are advised to go to the hospital in time for examination and confirmation, and can wear lenses to correct the problem, and use anti-cataract eye drops to treat the problem appropriately. Physiological myopia may also be caused by frequent late nights and insomnia, and patients are advised to wear appropriate myopia glasses and avoid eye fatigue in life. The cause of myopia is mostly due to the long anterior-posterior axis of the eyeball, followed by the strong refractive power of the eye, which is manifested by the symptom of not being able to see distant objects, but being able to see near objects. It is recommended not to watch TV and computer for a long time, pay attention to rest, look at more green plants, and eat more bright food. Elderly patients with myopia symptoms are advised to go to the hospital for examination as soon as possible to clarify the cause of the disease and follow the doctor’s instructions for treatment and correction.
