Revolutionary Fresnel Lenses: From Lighthouses to Headlights In the 1800s, Augustin-Jean Fresnel revolutionized the way we use light with the invention of Fresnel lens! Thanks to his prismatic design, we now have headlights, stage lights, house lights, dock lights, and more - all based on this innovative technology! #fresnellenses #augustinfresnel #revolutionarytech #jupiterlighthouse #jupterflorida #soflo | Jupiter Inlet Lighthouse & Museum
