The earliest microscopes used spherical lenses to magnify their subjects, which is why most of these rudimentary tools relied on two optical components; a single spherical lens focuses light poorly, but that fuzziness can be corrected by supplementing the first lens with another piece of optical glass. Early optics experts discovered that using an aspherical lens in the microscope immediately improved performance by eliminating those spherical aberrations, or the loss of image definition.
