MANUFACTURING FRESNEL LENSES. The first Fresnel lenses were made by tediously grinding and polishing glass by hand. Eventually, molten glass was poured into molds, but it was only with the development of optical-quality plastics and injection-molding technology in the 20 th-century that the use of Fresnel lenses in many industrial and commercial applications became practical.
