A patient observes images of reading materials through an emergent ray opening, so that the patient can normally read and write visual objects in a long sight distance and in a good sitting posture; the patient observes the images of the reading materials through the upper part of the cover so as to get the distance vision capacity trained; the patient observes moving objects through the emergent ray opening, therefore, asthenopia brought by long-time reading and writing of the visual objects is relieved.
