Improved cover essentially characterized by the fact that as a first operative phase, manual or mechanical cutting of plastic sheet, resistant synthetic material, under pre-established pattern and in one piece and that have to form the outer covering of the case itself and separately they cut by the same means, sheets of the same characteristics, but that present one of their faces in an antifrictional filiform arrangement for protection of the own glasses, doing simultaneously the cutting of plates of material of buffering properties, of the same forms, but of minors dimensions and that have to form an internal cushion support anti-shock, placing in superposition the pieces cut and proceeding to the union of the external or internal sheet perimetrically by means of an electronic welding process, which by melting the plastic is reduced to a single body, with separation between the rest of its pla we, sector that occupies the aforementioned padding, also making welds on the edges that define the structural formation of the case and acting said welded reinforcement zones.
