How do I make a swimming goggle fog free?
Swimming goggles can become foggy while swimming due to the temperature difference between the water and the air. To prevent the fogging, the goggles should be treated with an anti-fog solution, such as a baby shampoo and warm water mixture or a commercial anti-fog solution, and then rinsed thoroughly. Additionally, swimmers should apply a thin coat of saliva or a commercial anti-fog solution to the inside of the lenses before each swim. The lenses should also be rinsed with a stream of water after each use. Lastly, the goggles should be stored in a cool and dry place when not in use.
