Snorkeling can be a thrill and diving underwater can be great, but it becomes annoying when your dive mask gets foggy! Also, foggy lenses are hindered to show you the beautiful underwater world. Fortunately there are a few simple tricks you can utilize to prevent your dive mask from fogging up and to ensure your diving enjoyment each and every time.


A good tip to prevent fogging on your dive mask is to use a special defogging solution. These solutions are designed to prevent fog from forming on your mask. Just put a tag end of the solution inside your mask, rub it and rinse it out before you dive. This forms a thin film that maintains a clear visual underwater.

A solution of baby shampoo mixed with water can also be used to clean your lenses before entering the water. This gentle blend leaves your mask squeaky clean and your underwater view bright.
