How to deal with glasses fogging?

1. Buy anti-fog lenses. Patent anti-fog lenses are generally coated with a special hydrophilic anti-fog film, which can effectively reduce the probability of fogging and the anti-fog effect can reach 85%. However, different brands of anti-fog lenses may have different anti-fog effects.

2. Use special anti-fog cleaner for glasses. The special anti-fog cleaner for glasses can form a dense, ultra-thin and ultra-transparent biological coating on the lens surface, and transform the fog drops into a transparent micro-glass layer, thus achieving the purpose of anti-fog.

3. Self-made anti-fog. Mix 30 ml glycerol with 10 ml soap solution, then add a few drops of turpentine and stir well. When in use, the antifogging agent is coated on the lens, and then it is dried with glasses cloth. General anti-fog effect can last for 3-4 hours.

4. Other simple methods. Apply soap, detergent, shower gel and other surface active substances to the lens, then wipe it evenly and polish it with glasses cloth. General anti-fog duration can reach 2-3 hours.

Self-made antifogging is simple, but washing products such as soap liquid often have a certain corrosive effect, which may damage the coating on the lens surface, thus destroying the radiation protection and scratch protection functions of the coating. Therefore, frequent use is not recommended.
