This invention refers to a mould for making products with high-durability areas along preferential directions, particularly contact lenses. The mould includes two half moulds that define a cavity for forming the piece moulding the plastic of the synthetic material placed in between. There are grooves in the said cavity down which the material being stamped runs while it is being moulded. The grooves have parts which develop substantially parallel to the preferred areas of durability desired.<IMAGE>
