The functions of protective goggles

1. Avoid radiation damage to the eyes

Protective glasses are a kind of filter that can absorb certain wavelengths of light. Light, thereby allowing other wavelengths of light to pass through, showing a certain color. The color presented is the color of the transmitted light, thereby changing the transmitted light intensity and spectrum to avoid radiation damage to the eyes. For example, welding and welding goggles can effectively protect the eyes. Welding personnel are not exposed to strong light during the welding process, thereby protecting their eyes.

2. Prevent virus infection

The lenses of goggles can isolate the virus from entering the conjunctiva. It is an important protective equipment to protect the eyes from virus infection during the period of high virus incidence. General medical staff due to When in direct contact with patients, you need to wear goggles for protection to avoid contracting the virus.

Generally, the standard for ordinary goggles to prevent foreign matter splashing is 24 months. , if used frequently, one pair should be replaced every 3 months. In addition, the goggles are used for too long or improperly, causing the lenses to be rough and damaged, leaving scratches and affecting the wearer's vision.

Go to the outer circulation to wipe the lens, do not wipe the lens front and back, just wipe it clean. Do not use rough cloth, newspapers or clothes to wipe the lenses, as this will also cause damage to the lens coating.

4. Or soak the goggles in acidic oxidation potential water for 5 minutes to achieve a clean mirror surface and clear vision. The main component of acidic oxidation potential water is hypochlorous acid, which has a good inactivation effect on viruses.

5. Finally, wash your hands with soap or spray alcohol to disinfect them.
