1. Buy anti-fog lenses. Patented anti-fog lenses are generally coated with a special hydrophilic anti-fog film layer, which can effectively reduce the chance of fog generation, and the anti-fog effect can reach 85%. However, the anti-fog effects of different brands of anti-fog lenses may be different.
2. Use special anti-fog cleaner for glasses. Special anti-fog cleaner for glasses can form a dense, ultra-thin, ultra-transparent biological coating on the lens surface, converting fog droplets into a transparent micro-glass layer to achieve anti-fog purposes.
3. Make your own anti-fog water. Mix 30 ml of glycerin and 10 ml of soap solution, then add a few drops of turpentine and stir evenly. When using, apply this anti-fog water on the lenses and then wipe them dry with a glasses cloth. Generally, the anti-fog effect can last for 3-4 hours.
4. Other simple methods. Apply surface-active substances such as soap, dishwashing liquid, or shower gel to the lenses, then wipe them evenly with a glasses cloth and polish them. Generally, the anti-fog duration can reach 2-3 hours.
Although homemade anti-fog water is simple, the soap liquid and other cleaning products used often have a certain corrosive effect, which may damage the coating on the surface of the lens, thereby destroying the radiation protection and scratch resistance of the coating. and other functions. Therefore it is not recommended to use it frequently.
