About the end of the thirteenth century, the lack of homogeneity of high-quality optical glass, glasses were invented only correct presbyopia. Until 1608, Calileo telescope, optical quality glass made very high demands, thereby promoting the process of lens materials breakthrough. The seventeenth century, Fraunhofer study the refraction of the glass on the solar spectrum, dispersion and dispersion correction of the telescope lens. 1757, Dolland with crown glass, flint glass lens chromatic aberration-free. 1880, Abbe introduced a high refractive index of optical glass, there was no significant corresponding increase in the dispersion. Since then, the German company Carl Zeiss lens to produce such glass. Into the twentieth century, mass production of optical glass, wide variety, as a spectacle lens material, the quality requirements in order to have good optical performance-based, such as refractive index, dispersion and so on. Compared with optical glass, resin, very brief history of lenses. As World War I, the optical glass industry to promote the development of the United States, World War II to promote industrial development in the United States resin. In 1947, Colombia resin (Columbia Resin 39, CR-39) began as a spectacle lens material application; in 1978, polycarbonate resin (Polycarbonate Resin) come out. Because the U.S. FDA on the lens impact resistance testing requirements, a large lens of popular and effective fashion can be stained, resin lens increasing demand for market share has expanded each year.
