The present application belongs to the technical field of glass surface treatment and precision manufacturing of coated glass lenses, and particularly relates to a method and device for simultaneously surface treatment and mold pressing manufacturing of coated glass lenses. The method is applied to the heating stage of glass lens mold pressing. In the stage, the glass preform is heated and surface treated simultaneously to ensure that the glass surface composition remains stable and surface defects of the mold pressed glass lens are inhibited. When the glass preform is heated, the optical surface of the glass preform is not in contact with the inner surface of the mold cavity. The surface treatment is to expose the optical surface of the glass preform to a specific gas atmosphere. The gas is used to reduce the glass surface temperature and carry away part of the unstable substances on the surface by flowing. The present application improves the surface state of the glass preform, optimizes the heating mode of the glass preform, avoids long-time contact between the glass and the mold, and thus solves the problems of surface defects of the mold pressed glass and poor coating quality, effectively improving the surface quality and yield of the coated glass lens.
