Swim goggles are essential for swimmers, but can often be hindered by fogging up. This article explains how to prevent this from occurring. Firstly, it is important to purchase a quality pair of goggles with a good seal and anti-fogging coating. Secondly, swimmers should rinse the goggles with clean water before and after each swim. This will remove any oils or residue which can cause fogging. Finally, a small amount of antifog solution can be applied to the inside of the lenses to further prevent fogging. Following these steps will help ensure your goggles remain fog-free during your swim.
