   Pulite Anti-High-Frequency Microwave Radiation Glasses are protective goggles designed to shield against electromagnetic wave radiation in work environments, effectively blocking and reflecting microwave and radio frequency radiation to protect the eyes. The glasses feature a universal structure with plano lenses and high-transmittance coating technology, making them similar in use and wear to ordinary glasses. However, their unique anti-radiation properties require specific care and maintenance. These glasses are widely used and highly recognized in military units, IT companies, and microwave and radio frequency product enterprises in cities such as Chengdu, Shanghai, Chongqing, Mianyang, Xi'an, Shenyang, and Nanjing.
Anti-microwave goggles are protective glasses worn in work environments where microwave radiation intensity exceeds standards. They consist of a filter lens and a frame. Anti-microwave glasses effectively block and shield microwave radiation, blue light radiation, and other electromagnetic waves.
    The filter lens of anti-microwave glasses is made of ordinary transparent material, with a semi-conductive tin oxide (SnO2) film coated on the inner surface to reflect frontal microwave radiation.
The frame is made of microwave-absorbing plastic, designed with wide sides and embedded with fine copper wire mesh for good conductivity, which reflects side microwave radiation. These goggles can achieve reflection and absorption effects of up to 25dB for microwave radiation in the 3–5cm wavelength range.
    Alternatively, copper wires with a diameter of 0.07–0.14mm can be used to create a mesh with 560–180 openings per square centimeter. Goggles made with this mesh can prevent microwave radiation and reflection. Additionally, aluminum-coated organic glass face shields can provide microwave protection effects of 15–30dB.
When selecting anti-microwave goggles, key factors to check include the microwave attenuation value, appearance quality, absence of scratches, bubbles, or cracks on the filter lens, smoothness, structure, comfort, and whether the product has been tested by relevant authorities.

   The following are the permissible microwave radiation standards for the human body, which can guide the selection of anti-microwave goggles:
GB10436-89 stipulates that the average power density of microwave radiation permitted at the operator's position must meet the following standards:
1. Continuous wave: 8-hour exposure is 50 μW/cm2; for exposures less or greater than 8 hours, the daily dose must not exceed 400 μW·h/cm2.
2. Pulsed wave (fixed radiation): 8-hour exposure is 25 μW/cm2; for exposures less or greater than 8 hours, the daily dose must not exceed 200 μW·h/cm2.
3. Local limb radiation (regardless of continuous or pulsed wave): 8-hour exposure is 500 μW/cm2; for exposures less or greater than 8 hours, the daily dose must not exceed 400 μW·h/cm2.
4. Short-term exposure: When working in environments with radiation intensity greater than 1 mW/cm2, in addition to calculating exposure time based on the daily permissible dose, personal protective equipment must be used, but the maximum radiation intensity at the operator's position must not exceed 5 mW/cm2.
  Anti-microwave glasses are a type of professional protective eyewear primarily used in various environments where electromagnetic waves are present. They are applicable in daily office settings with computers, printers, fax machines, electromagnetic radiation in various computer rooms and laboratories, testing workshops, electronic workshops, banks, financial institutions, microwave stations, radar stations, and various types of naval vessels.
