Common types and use of protective eyewear
① ordinary optical glass mirror. By ordinary optical glass lenses, prevention turners, grinders, milling, drilling workers, boring work, riveter, sand work, modeling work by mechanical injury and acid-base operations, laboratory, sample pH burns, driver Anti-foreign matter into the eyes.
② UV mirror. In the optical fire goggle melt into the UV-absorbing chemicals, to visible light, ultraviolet absorption rate. Depending on the type of work required, the lenses were installed in the frame, mask or helmet. LCD is now made of welded mirror glare encountered in 0.001 ~ 0.002s blacked out momentarily, protective welding operator does not occur electric ophthalmia.
③ high temperature protective glasses. Lens by a high-temperature glass, can absorb some infrared furnace for smelting operations workers, fireman, blacksmith, watching fire workers, Castor, glaziers and so on.
④ radiation goggles. Is added to the optical glass of lead, for Χ rays, γ-rays, α-rays, β-rays workers.
⑤ microwave goggles. Is the outer surface of the optical glass with a layer of stannous oxide thin metal powder, for microwave operation.
⑥ against laser mirrors. Shape for the goggle type, multi-purpose lenses made of polymer composite materials, can be replaced. According to the principle against laser radiation, anti-laser glasses into reflective, absorptive, reflective absorption, explosion-type, photochemical reaction type and color glass type.
Note the use of protective eyewear
Protective glasses and more material made from glass, should be taken to avoid collision fragmentation. High-speed operation in the event of splashes, the lens may be broken, and damage the eyes, precautions must be taken, such as the lens plus a layer of metal mesh. Frames while preventing damage to the lens by grinding, into the box when not in use. Anti-radiation lead ions inside the lens, easily oxidized to milky white affect light transmission, should be replaced. Anti-laser glasses were marked by anti-wavelength optical density values and not misused.
