A device for protection against strong light for holes in buildings or the like, consisting of at least two plates of transparent material arranged essentially parallel to each other and at a reciprocal distance and in a liquid which can be introduced between the plates and which includes on the transparency of the assembly, in which the liquid can be driven by means of a pump or the like from a container to the space between the plates or, respectively, extracted from said space, characterized in that at least one of the plates has inequalities that they reduce their transparency on the surface turned towards the space between the plates and because the liquid has a refractive index that corresponds approximately to that of the material of the plates.
