A device for protecting users from the radiation generated by screens such as computer monitors and television sets is disclosed. The device comprises a double transparent filter consisting of two walls of different thicknesses, i.e. a clear convex rear wall and a thicker smoked front wall. The frame is made of sealing rubber with a U-shaped cross-section and twin internal grooves. The gap between the walls is filled with water and encloses a bare copper wire for earthing. The device may be placed against the uprights surrounding the screen of the apparatus in question, and is held in a position parallel to the screen by two rails fastened to the uprights. Said device is particularly suitable for users of apparatuses with screens, such as computer monitors, television sets, videotex terminals, video game consoles, etc.
