This 7.25 x 10.25 inches magnifying plastic sheet is great for optics / science projects, for reading or just fun. A French physicist named Augustin Fresnel invented this lens in 1822 to be used in lighthouses. The construction of Fresnel lens is quite interesting as it allows magnification just like regular glass lenses do but it can be as thin as paper!
