Wash the glasses first, dry the lenses without dust and grease, then blow air on the lenses, and then wipe them with this cloth, which can really make the lenses fogged, but only if the lenses are kept clean. If the lenses are dirty, dusty and greasy, they will fog again.
Methods to prevent glass from fogging;
1, anti-fog glasses cloth
Anti-fog glasses cloth is made of anti-fog and antibacterial nano-coating. After spraying this hydrophilic polymer coating, water vapor will not form water mist when contacting the coating, but will slide down in the form of water droplets. Using this kind of anti-fog glasses cloth to wipe the inside of goggles can keep fogging for 5-8 hours.
2, anti-fog spray
Similarly, anti-fog spray can also be used for anti-fog goggles.
How to use:
Cleaning the lens, and drying after cleaning; Spray anti-fog agent or spray, the goggles are closed, just apply the inner wall and dry it after application. After drying, if there are traces, gently wipe them with a mirror cloth. If there are no traces, don't wipe them. Don't rub it repeatedly, the anti-fog layer won't work.
