Myopia is caused by changes in the refractive system of the eye, daily hot compresses have no therapeutic effect on myopia, but hot compresses can relieve visual fatigue. Myopia can be categorized into true myopia and pseudomyopia according to different causes. True myopia is caused by organic changes in the refractive system of the eyes, and pseudomyopia is caused by ciliary muscle spasm due to eye fatigue. For true myopia, because of the organic changes that have occurred, through hot compresses can not be essentially changed, so there is no effect. For pseudomyopia, hot compresses can relieve the fatigue of the muscles around the eyes, which can reduce the symptoms of visual fatigue, but it can not be completely cured, patients need to develop good eye habits. It is recommended that patients with myopia consult a doctor in time to assess their condition and choose the appropriate treatment under the guidance of the doctor.
