As a very important protective equipment in daily life, eye protection has attracted more and more attention from people. Do you know that there are many classifications of eye protection? What are its characteristics?
       1. Dust proof glasses
       Dust proof glasses are used in environments with a lot of dust, and generally do not require high lens fastness. Whether it is eye mask or flat mirror, they are made of ordinary flat glass lenses.
       2. Anti chemical
       The lenses of anti chemical glasses are resistant to acid, alkali, and corrosion, which are not possessed by other glasses. Therefore, every worker who needs to wear protective goggles should be aware of the harmful factors in their work environment, wear appropriate safety goggles, and not wear them randomly.
       3. Arc radiation
       Workers engaged in welding, gas welding, steelmaking, and glass blowing operations should wear anti arc radiation glasses. However, the color of the lenses in anti arc radiation glasses varies depending on different requirements, and the selection should be based on the intensity of the arc light during operation. The arc light should be strong and the color should be dark; On the contrary, light colored lenses should be chosen. If the arc light is strong and light colored protective glasses are worn, some infrared rays will penetrate the lenses and irritate and damage the eyes, which can lead to occupational cataracts in the long term; On the contrary, if the arc light is weak and dark safety goggles are worn for a long time, it will cause a significant decrease in vision.
       4. Impact resistance
       Anti impact glasses are used to prevent small particles from flying through the eyes, and their lenses are required to be impact resistant. For example, drivers, sanders, and stoners should wear anti impact glasses. If these workers wear general dust-proof glasses, the iron sand and gravel flying through the glasses will shatter and cause greater damage to the eyes.
       Features of protective goggles:
       1. Metal mesh masks can also prevent microwave radiation.
       2. A face mask that prevents group debris and chemical solutions from splashing into the eyes and damaging the face, made of lightweight transparent plastic, often made of polycarbonate and other plastics. The two sides and lower ends of the mask extend towards the ears and the lower part of the forehead towards the neck, allowing the mask to cover the face more comprehensively and enhance the protective effect.
       3. The welding face mask is made of a certain thickness of hard paper fiber, which is lightweight, heat-resistant, and has good electrical insulation.
       4. In addition to the aluminum foil mask mentioned in the thermal suit, the thermal mask can also be made of a single or double layer of metal mesh, but the double layer is better, which can block some radiation and dissipate heat in the air. If chrome or nickel plating is possible, it can enhance the reflection and heat protection effect, and prevent rusting.

       Radiation resistant protective glasses are used to defend against the harm of excessive ultraviolet radiation to the eyes. The lenses are made of special glass that can reflect or absorb radiation, but can transmit a certain amount of visible light. The lenses are coated with bright chromium, nickel, mercury or silver metal films, which can reflect radiation lines; Blue lenses absorb infrared rays, yellow green lenses absorb both ultraviolet and infrared rays, and colorless lead lenses absorb X-rays and γ Radiation. For example, common welding glasses have relatively low requirements for the transmittance of the lens, so the color of the lens is mostly ink; Laser protective glasses, as the name suggests, can prevent laser radiation from the glasses, so high requirements are placed on the lenses, such as the selection of light sources, attenuation rate, light reaction time, light density, and light transmission effect. Different nanometers (nm) of lasers require lenses of different wavelengths.

       In short, protective glasses are very important. When choosing, everyone must choose glasses that are suitable for their function and purpose, so as to achieve useful results.
