The Czech Republic is the first country with a law prohibiting light pollution, notes the Berliner Morgenpost. The law, known as the Protection of the Atmosphere Act, came into force on June 1, 2002. It has found wide support among astronomers and also the population in general. The law defines light pollution as “every form of illumination by artificial light that is dispersed outside the areas it is dedicated to, particularly if directed above the level of the horizon.”

Citizens and organizations are obliged to reduce stray light, which impedes observation of the night sky, by using shielded light fixtures. Even prior to June 1, the use of such fixtures in downtown Brno had markedly reduced stray light. “The improvement is spectacular,” said Czech astronomer Jan Hollan.
