In the manufacture of safety glasses, all the components fulfill their function. None of them are assembled without first passing various stress tests<\/strong>.<\/p> \n \n

A shock and impact resistant frame is essential in this type of glasses. But resistant crystals are one of the most important protection elements to keep your eyes safe.<\/p> \n \n

Do you want to know what types of material are used to make the lenses of safety glasses? We’ll tell you then.<\/p> \n \n

Work protection glasses with resistant glasses<\/strong><\/h2> \n \n

Protective lenses can be made with three types of materials:<\/p> \n \n

    \n
  1. Organic or CR-39<\/strong>, ideal for\u00a0adding prescription<\/li> \n
  2. Polycarbonate or PC<\/strong>, very good for neutral and prescription lens<\/li> \n
  3. Mineral,<\/strong> excellent in neutral and graduated<\/li> \n<\/ol> \n \n

    Each material has characteristics that make it unique. All three are worn in work safety glasses.<\/p> \n \n

    Organic Lens<\/strong><\/h3> \n \n

    The first company to bring low-weight plastic lenses to market was the Armorlite Lens Company of California. It was in 1947.<\/p> \n \n

    They were the pioneers in making organic crystals. They made them with a plastic polymer called CR-39. This material is twice as impact resistant as mineral lenses. In addition, it is more durable and resists chemical splashes (anti-liquid).<\/strong><\/p> \n \n

    CR-39 lenses can be put on all kinds of frames. They adapt without problem to any model of safety glasses. They are commonly used for prescription lenses since their optics are good and resistant.<\/p> \n \n

    Its main feature is that it weighs very little. This makes protective glasses with organic lenses light and comfortable. A curiosity:<\/strong> organic lenses can be tinted in any color. Unlike polycarbonate or mineral, they only admit certain shades.<\/p> \n \n
