The invention relates to a medical appliance and vision correction glasses. According to the technical scheme, the glasses comprise a glass body which is characterized in that there are three layers of structures in the whole glasses, the upper layer is a filter layer, the middle layer is a convex lens, the lower layer is a triangular prism, a cavity structure is formed in the portion where the lenses and a glass frame are connected, corresponding to a nose pad, the nose pad is connected with the cavity structure through a spring clamping groove, and the nose pad and the glass body form a whole. The vision correction glasses have the advantages that the nose pad is a movable and selectable structure, when vision correction is carried out, a correction person selects a suitable nose pad according to his or her own needs, and therefore the situation is avoided that because the correction duration is too long, the nose bridge does not feel comfortable, which is caused by long-term compression on the nose bridge from the nose pad, and consequently the vision correction effect is affected. At the same time, multiple composite structures of the glasses can be used for improving the vision correction effect.
