Neutral optical glass lens surface scratches species

[Zhou Keven]

"Neutral optical glass" either inorganic material or organic material, optical lenses, in everyday use, due to friction with dirt or gravel can cause wear lenses, the lens surface scratches. Compared to glass, rigid degree of organic materials is relatively low, more susceptible to scratches. "Neutral optical glass" through a microscope, we can observe scratch the lens surface is divided into two types, one is generated due to scratches gravel, shallow and small, wearing glasses is not easy to detect; another "Neutral optical glass" species are scratching gravel produced by the larger, deep and surrounding rough, in the central region will affect vision.
