Protective visors are more effective than masks since they protect the wearer from possible droplets emitted immediately after a cough by a person nearby. Since they are either expensive, unavailable and should be reserved for caregivers, I came up with the following idea.

A cheap and 'chic' face shield (?! ☺️). All you need is a cap, a bandana or a sweatband, 6 buttons, sewing thread, a punching machine and a transparent A4 sheet (thicker, better). Since most of us have this at home, the cost is zero or less than € 1.
