Anti-microwave goggles are protective glasses worn in workplaces where microwave radiation intensity exceeds standard levels. They consist of filter lenses and a frame. These glasses effectively block electromagnetic waves such as microwave radiation and blue light radiation.
The filter lenses of anti-microwave glasses use ordinary transparent materials as the lens, with a semi-conductive tin oxide (SnO2) film coated on the inner surface to reflect frontal microwaves.
The frame is made of microwave-absorbing plastic, designed with wide sides and embedded with fine copper wire mesh with good conductivity to reflect side microwaves. These goggles achieve a reflection and absorption effect of up to 20dB for microwave radiation in the 3–5cm wavelength range.
Additionally, copper wires with a diameter of 0.07–0.14mm can be used to create a mesh of 560–180 holes per square centimeter. Goggles made with this mesh can prevent microwave radiation and reflection. There are also face shields made of aluminum-coated organic glass, offering microwave protection of 15–30dB.
When purchasing anti-microwave goggles, key factors to check include the microwave attenuation value, appearance quality, absence of scratches, bubbles, or cracks on the filter lenses, smoothness, structure, comfort when worn, and whether the product has been tested by relevant authorities.

Below are the permissible microwave radiation standards for the human body, which can be used as a reference when purchasing 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 (no distinction between continuous and pulsed waves): 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 permissible daily dose, personal protective equipment must be used. However, 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, among others.
