Protective arrangement of light for glasses, characterized in that the front and the component rods of a transparent type spectacle have such a constitution that it confers them a gradual variation in the transparency by a change of chromatic tone, from points of greater intensity to other points of less intensity, of luck; that the darker zones correspond to the outer flanks of the hoops and to the front of the rods, while the zones of greater clarity correspond to the bridge between rings, to the inner flank of the same, and to the back of the rods, all this in order that, in the event of possible light emissions in the form of beams or flashes from the side or rear areas of the user of the glasses, they are reflected in the area of greater darkness and are attenuated in such a way that they are harmless for vision.
