Fresnel Lighthouse Lens Smithsonian's History Explorer

In the early nineteenth century, lighthouses in the United States were considered inferior to those in France and England. American mariners complained about the quality of the light emanating from local lighthouse towers, arguing that European lighthouses were more effective at shining bright beams of light over long distances. While American lighthouses relied on lamps and mirrors to direct mariners, European lighthouses were equipped with compact lenses that could shine for miles.
