Ski goggles are a must-have item for having a safe and comfortable skiing experience. While choosing a ski goggle, you must be wondering – do ski goggles fog up? How to stop ski goggles from fogging? Let’s take a look at each of your queries thoroughly.

Do ski goggles fog up?

Almost every type of ski goggles fog up, especially those not made of non-fog material. Ski goggles are usually tight-fitting. Due to the tight-fitting, air can’t pass around it, and warm air released from your body clings to the inner part of the ski goggle as tiny water droplets.

The main function of ski goggles is to protect your eyes from snow, dust, and wind. So, they fit tightly with the forehead to prevent anything from entering the eyes.

As the ski goggles are normally sealed, warm air from your body collides with the interior of the goggles that have been chilled by sub-zero temperatures of the snow. This makes the water in the air condense into small droplets that adhere to the lens, blocking your vision.

Why are my ski goggles fogging up? – what causes ski goggles to fog

The phase change of vapor:

The ski goggles fog up when matter undergoes a phase shift. When the water vapor from breathing and sweat from your forehead comes in contact with the lenses, it cools down.

The temperature of the lenses of the ski goggles becomes very low as they are used for skiing in the snow.

When the warm vapor comes into contact with the cold lenses, it causes a phase shift and transforms into a liquid. This liquid makes the glass blurry and obstructs the vision.

Exhaled air entering the goggles:

While skiing, most of us use a face mask to remain warm in the snow. If the air exhaled through the mask enters the goggles, they usually fog up.

The reason behind this is that the breath is usually quite warm, and the glass of the ski goggles becomes cold. So, the air condenses into tiny drops that stick to the lens and makes it foggy.

How to keep ski goggles from fogging?

The recently launched ski goggles are mostly made with non-fog materials. No matter what kind of ski goggles you have, nature will still find a way to fog them up.

By preventing the ski goggles from fogging, you can have clear visibility while skiing in the snow. It will help you to have an incredible skiing experience. Let’s have a look at how to keep your ski goggles from fogging.

Stay in motion:

Staying motionless might cause your goggles to fog up rapidly, so try to keep on skiing while wearing the ski goggles. It will make sure that the inside and outside of the goggles remain at the same temperature.

On the chairlift, this is obviously tough, but if your goggles are adequately ventilated, your goggles should be alright. When you lift off from the chairlift, the goggles might appear foggy to you, but as you speed up, the fog will disappear.

It’s vital to remember that if you have fallen and are thrashing yourself in the snow attempting to get back up, you’re exposing yourself to fogged ski goggles.

The more you will struggle, the more your goggles will fog up. So, if you fall on the snow, take your time getting up.

Don’t keep the ski goggle on your forehead:

Ski goggles fog up mainly due to the warm air within your goggles mixed with cold air on the exterior. If you keep your ski goggles on your forehead, then it will most likely sweat and will release hot and humid air, which will fog it up.

Don’t overdress:

Overdressing, as ridiculous as it may sound, can be the cause of fogged goggles. It can cause a higher body heat, resulting in a significant temperature difference between the interior of your ski goggles and the air outside.

The easiest method to avoid this is to check the weather forecast before going skiing and then dress appropriately. You want to wear enough layers to stay comfortable while waiting in line for the elevator, rather than overdressing and sweating.

If you’re standing in the lift queue after a spectacular descent, letting off some steam is a good idea. To release some body heat, you can use pit zips on the underarm for ventilation if you feel warm.

Don’t tuck in your face mask:

Face masks are wonderful for keeping warm but don’t tuck them under your goggles since moisture and hot air from your breath can flow up to your goggles. It will potentially fog up your ski goggles.

If the weather gets extremely cold, tuck the tiniest piece of material over your nose, but not entirely between the foam cushioning.

Ensure the vents are open and working:

Most ski goggles feature vents to ventilate warm air from them and prevent the build-up of moisture inside the goggles.

Your body heat will cause the air inside your eyewear to heat up if your goggles’ vents are closed. Because that warm, wet air has nowhere to go, condensation will develop on the inside of the goggle. So, always remember to open the vents while skiing. 

Bring an extra pair:

An extra pair of ski goggles will come in handy to prevent them from fogging. The reason behind this is that it takes a lot of time to dry the ski goggles as they contain foam around the lens.

There’s nothing you can do if the inside foam pieces become wet from time to time. So, if you have a spare on hand, you can go for another round of skiing without any issues.

That being said, it doesn’t have to be a high-priced pair. Skiing with dry and inexpensive eyewear is preferable to without ski goggles at all.

Why do ski goggles fog up between lenses?

Ski goggles fog up between lenses mainly because of your body heat, sweat, and exhaled air. They increase the temperature and moisture inside the ski goggles.

The warm moist air within the ski goggles collides with the outside environment, which is exposed to the freezing temperature. As a result, condensation forms on the interior of the lens, and the ski goggles fog up.

Can I use anti fog on ski goggles?
