What innovative devise did Stevenson help develop to improve maritime safety?

  • Marine compass

  • Life jacket

  • Marine chronometer

  • Fresnel lens

Answer

The Fresnel lens, developed with significant contributions from Robert Stevenson, revolutionized maritime safety by providing a compact and efficient means to magnify light for lighthouses. Unlike traditional parabolic reflectors, Fresnel lenses utilize concentric rings of prisms to refract and concentrate light into a powerful beam, increasing the visibility and range of lighthouses. This innovation dramatically enhanced navigation, reducing accidents and saving countless lives at sea.
