What Causes Ski Goggles To Fog?

Outdoor Master Goggles Stay Fog-Free

Ski goggle lenses fog when water vapor condenses onto them. The condensation can come from your breath or sweat, but it can also be the result of ambient humidity landing on the lens.

The vapor cools when it lands on the lens and transforms into tiny water droplets, fogging up your lens, making all that fancy lens technology useless.

How quickly your ski goggle lens fogs up depends on the temperature and the humidity. Therefore, your lens will fog more rapidly in colder weather.

How hard you're physically working will also affect how quickly your goggles will fog. If you're exerting yourself to a point where you're sweating a lot, the increased humidity escaping from your ski jacket will cause more vapor to land on your lens.

How Anti Fog Ski Goggles Work

All good ski goggles should have ways to keep them clear from fog. Therefore, manufacturers of quality ski goggles incorporate various characteristics and features to keep your vision as clear as possible. Here's how they do it:

Multiple Lenses

Most anti fog ski goggles use two lenses. The lenses are arranged like double-glazed windows, creating a thin dead air space between them. This system helps to regulate the lens's temperature, as the lens closer to your face is warmer. Therefore, there is no cold surface for the water droplets to condense onto.

Anti Fog Lens Coating

Another feature of anti fog ski goggles is their lens coating. This ingenious coating goes a long way to prevent water droplets from condensing on the lens's surface.

If your ski goggles don't have an anti fog lens coating, you can buy spray-on treatments from most ski shops or online. However, you need to be aware that these spray-on coatings must be topped up from time to time. Also, some treatments are unsuitable for goggles with mirrored lenses, so be careful what you use.

Ventilation

One of the most critical features of anti fog ski goggles is how well they are ventilated. Good ventilation helps to keep your goggles clear by allowing the damp air inside them to escape.

You will see air vents located around the frame or in the lens itself. Most ski helmets have strategically placed vents allowing air to flow into your goggles. If you match your goggles and helmet, the vents complement each other, giving you superior anti fogging.

How Outdoor Master Goggles Stay Fog-Free

Outdoor Master Goggles Stay Fog-Free

One of the main features of Outdoor Master anti fog ski goggles is the lens material. Each lens is made from CAP (cellulose acetate propionate), a plant-based product made from wood and cotton extract.

CAP gives the lens an uneven surface, allowing it to absorb water like a sponge. The lens also has an additional coating that enhances this water absorption, contributing to the anti fogging properties of the lens.

Of course, the lens can only absorb so much water. But, if it fogs up due to excessive moisture, you can wait for it to dry out on its own or dab it with a dry cloth.

Another way Outdoor Master ski goggles stay clear is with their dual lens design. The double layer creates a gap insulating the lens to prevent water vapor from condensing on the surface, fogging it up.

However, if the lens does fog up in extreme conditions, Outdoor Master goggles have interchangeable lenses. The system allows you to quickly switch your fogged-up lens for a clear one.

All these features mean that Outdoor Master ski goggles comply with the European EN174 standard.

But, Outdoor Master's Pro Plus ski goggles and Ultra ski gogglesand eco friendly ski goggles use 3X anti fog. This means their anti fogging properties exceed the standard by three times, making them among the highest performing on the market.
