Light pollution is not just a concern for astronomers. Light shining into the eyes of pedestrians and drivers can reduce visibility. It also reduces night vision, which takes an hour (or more) to return after exposure to bright lights. Light directed out at the viewer (away from a building) causes areas of deep shadow; much home security lighting actually makes houses easier to be broken into, because intruders have more places to hide |
