How to Keep Swim Goggles from Fogging

Whether it happens on your opening dive or during the home stretch, there’s nothing worse than looking out of a pair of foggy goggles when you’re trying to get through a swim. Fog in your goggles can hamper your workout or even cost you a race. Learn how you can keep your goggles from fogging with these different methods.


Given that foggy goggles are usually caused by condensation, swimmers can lower their body heat a bit and slow down the buildup of condensation with a simple splash of cold water from the pool or the tap. By wetting your face with cold water before you put on your goggles, you can usually at least prevent that immediate burst of fog that sometimes occurs when you first jump in the water. Over time, though, as you continue to swim, your body will nevertheless heat up, meaning that the condensation may still occur eventually, so you may still find yourself searching for other solutions to your fogging issues.


While it might seem a little gross to some, there’s a good reason that professional swimmers are often seen spitting into their goggles as they ready for their races. The thin layer of moisture that this adds to goggles is actually a deterrent against fogging. If you’re willing to try it, simply add a small amount of saliva to each lens and ensure that it’s evenly spread across the surface before you head into the water.


As far as non-natural solutions to keeping your goggles from fogging go, you probably have a few options readily available in your home, or even already in your swim bag. Shampoo is one common solution for fogging. Add a small drop of shampoo to the surface of each lens and spread it around evenly. Rinse each lens to remove some of the shampoo, but not so much that you remove all of it, and you’re ready to go. While your regular shampoo will do the trick, you do need to be wary of leaving too much of it in your lenses and irritating your eyes. For this reason, many swimmers using this anti-fogging trick will opt for baby shampoo to help avoid this potential irritation in the water.

You can also use toothpaste to help prevent fogging. Simply add a small amount of paste to the inside of your lenses and gently brush it with a clean toothbrush. Rinse the paste away and you’ll still be left with a thin layer of it that helps keep your swim goggles from fogging.


The do-it-yourself solutions above are time-tested and used by many swimmers, but if you’re not having any luck or just want a simple, specialized fog solution, there are anti-fog sprays available to help. These sprays usually come in a small, portable bottle, and the application method is as easy as any of the other options laid out here. Simply spray a thin, even layer of anti-fogging spray to each lens, rinse, and you’re ready to swim.


While all of these methods are useful in their own right, there’s no substitute for having the right pair of goggles. Many of today’s top swim goggles offer built-in anti-fogging protection.
