How to Stop Swim Goggles from Fogging Up

Opening your eyes underwater without any protective gear will irritate. Swim goggles serve as eyeglasses underwater as it helps you see clearer when swimming and it also protects the eye from the dirt and chemicals of pool water.

Goggles have a suction-like material around the edges, so it prevents the water from coming in. Aside from purchasing good quality goggles, wearing it properly is essential to optimize its use. However, there are still inevitable factors that can affect your clear vision underwater.

What Causes Your Goggles to Fog Up?

Most, if not all, will agree that fog might still appear even if you have done everything to prevent it from happening. Generally, fog is created when a transparent surface condensate with the humidity of the surroundings. This is a result of the different temperatures of the surface which, in this case, your face (warmer) and the environment that surrounds you (water). Heat is then released as the surface recovers and tries to balance between the two. As a result, the water molecules evolve to gas and eventually turns into tiny water droplets which is what we call fog.

How To Stop Fogging Up Your Swim Goggles?

Nothing is more frustrating for swimmers than losing a clear vision underwater especially when you are training or worse, competing! You easily get distracted and it disturbs your rhythm and eventually loses your focus. Here are some preventive measures to avoid it:

1. Buy goggles with an anti-fog feature
With modern technology, an anti-fog feature in glasses and different kind of goggles are readily available in the market. The main mechanism of this technology is based on the concept to eventually reach and overcome the tension on the surface which will lead to the spreading of water until it disappears.

Most manufacturers apply and anti-fog coating called surfactant that decreases the surface tension so that there will be no moist build-up. The great thing about coated goggles is that the effect lasts longer.

2. Purchase some anti-fog spray 
Use an anti-fog spray Goggles with anti-fog coating can be expensive. If you want to save a few bucks, I recommend you to just work with the goggle you already have and just purchase an anti-fog spray. These solutions have agents and treatments that act on the surface area which inhibits the condensation.
Most of these spray coatings last for 2 to 3 months then you have re-coat. Lastly, exposing coated goggles to UV lights are also effective to activate the chemicals to prolong its effectivity.

Myth-buster: Do These DIY Defogging Fixes Work?

There is a couple of households and everyday items that supposedly serve as anti-fogging materials. Experts call these demisters and some people swear by it. Let us find out!

1. Spit on your goggles
I know it sounds gross, but some swimmers do this to remove the fog. The moisture of the saliva effectively cleanses the goggles and the fog disappears. However, this does not last long. Other than the fact that it cleans the surface area and is always readily available, there are no lasting effects to this solution.

2. Toothpaste
This has the same mechanism as the first item. It cleans the surface and can limit condensation but for a limited time only. Though you must be careful in choosing a regular toothpaste. Make sure that it is free from any abrasive contents such as beads that can potentially destroy the lenses of the goggles. Furthermore, refrain from using toothpaste on glasses with existing anti-fog coating because it may remove the coat.

3. Baby shampoo
Since baby shampoos are very mild and do not have abrasive contents, this can also be used to clean fogged-up goggles. Some also use a tiny amount of hair conditioner. The aim is that applying these will leave a thin layer of coat that may act as a protective film against the mist. Make sure to rinse properly as this may irritate your eyes.

4. Coldwater
Since the warmth of your face adds up to the fog build-up, it is just logical to bring down the temperature by splashing cold water to your face.
