Spending time doing outdoor winter activities like skiing and snowboarding is fun especially if you have a protective eyewear like a ski goggle to shield your eyes against UV lights, the wind, irritants, cold, and enhance your FOV (Field of View). However, accidents can happen due to goggle fogging especially if you’re a beginner and does not know how to keep ski goggles from fogging. But luckily, here are some pointers to keep your goggle fog-free.
A ski goggle serves as a protective eyewear and visibility enhancement. A well-made snow goggle does not only account for the sturdiness of its lens and its capability to protect the eyes from UV radiation, wind, cold and debris nor having the goggle lens interchangeable to accommodate the eye sight for a clear visibility under different weather conditions but should also feature an anti-fogging system.
It is inevitable for a snow goggle lens to fog. Fogging obscures your view and should definitely not occur especially when you are skiing, snowboarding or doing other winter activities requiring a snow goggle because you might be exposed to a possible accident or a fatal injury.
Fogging, what causes it?
As to why goggles fog up can be explained in one word – condensation. As you sweat or breathe, the warm, wet air condenses on the lenses covering it with steam because they’re colder. Generally, this occurs when the moist begins to take shape on the inside of the goggle lens due to warming, water or snow entering the goggles.
And if there is no provision for fresh air, the moisture is trapped creating tiny droplets of condensed water clinging onto the lens obscuring your view. Surprisingly, there are ways to avoid or get rid of this nuisance.
1. Avoiding Warm Air
There are circumstances to consider to keep the warm, moist air when you breathe beneath a goggle to prevent fogging.
- Goggles should not be worn on your forehead.
- Overdressing can rapidly produce sweat and heat especially when skiing.
- Goggles are worn inside a building before going outside.
- It shouldn’t be removed until you’re done skiing.
- Gaiters funnel warm air up under the goggles from your body.
- Moisture pervades through a breathable coat and freezes on goggles if you intend to place it in your coat’s pocket.
- The gap through which the warm air comes in should be filled up then.
- Air gaps can be fixed by making sure the goggles fit tightly to the contour of your face.
- The moist air when you breathe vents up beyond and not inside the goggles using balaclavas having lots of air holes and a snout extended.
- Excessive heat and sweating could also happen when hiking thus putting away your ski goggles might be a good idea.
2. Anti-fog Coating
If you find it impossible to evade warm air, you could try applying an anti-fog coating. It is applying anti-fog agents and treatments to the lenses. Tiny droplets of water are prevented from condensing on the surface of the lens thus the water vapor finds it difficult to affix itself to the lenses in the first place. Anti-fog coatings are also called non-mist coatings.
Cat Crap anti-fog cleaner makes a good anti-fog coating especially on eyeglasses if you wear one underneath your goggles. If your goggle lens already utilize an anti-fog coating then there’s no need to apply one. Alternatively, you could also try a TYR LAF Anti-Fog spray which coats and cleans the surface of the goggle lens in an instant.
Treating a transparent product to prevent fogging for many applications incorporating an increase in humidity and the change in temperature can be an evident edge.
Goggles need air-drying after every snow-related activity to stop it from fogging. If it’s too late to prevent the fog, you can always defog it by drying the lenses. To avoid invalidating the lens’ anti-fog treatment, it shouldn’t be left facing the ground to air-dry and shouldn’t be wiped but rather placed in a dry pocket or shaken to get some air flowing.
If it doesn’t work, you could always head inside to any establishment and allow the water to evaporate to dry the lenses. You can use the cafe/restaurant’s hand dryer or the salons’ hair dryer or blower (either of the implements should not be close enough to melt the lenses). After that, you can gently polish away any remaining moisture using a dry microfiber lens bag.
Usually, removing the goggles for a bit solves it. Air-drying dispels the foul smell the goggle emits when it is soaked in sweat.
A good ventilation system makes up a good ski goggle. The ventilation foam at the top and bottom of a goggle keeps an ample amount of air flowing through the inside of the goggles and releasing the moisture that can fog and freeze the lens.
It’s a must to check the goggle lens if you end up tumbling down in the snow to verify its state – is it clear or slowly fogging or fogging already? If it does fog, it is possible that some type of element: it could be the face mask, the helmet or a snow, blocks the vents forbidding an air to flow through.
If it is snow that’s causing the commotion, it’s most likely frozen and needs to be gently tapped. Moving and riding faster provides more ventilation.
5. Spare goggles and spare lenses
Bringing extra lenses for interchanging the other that got fogged or damaged can save you the hassle. The replacements should match the outdoor condition. If you do not have spare lenses or your snow goggle doesn’t come with replaceable lenses, you could always bring 1, 2 or more extra snow goggles instead.
You can utilize different snow goggles or lenses to suit different weather conditions: sunny, shady, misty or cloudy.
6. Buy Anti-fogging Ski Goggles
Modern design now includes a variety of features from UV400 protection treated polycarbonate lenses with vents to anti-fogging goggles with interchangeable lenses. A solid and superior PC double-layer lensed goggle is not only impact-resistant but also moist-absorbent, utilizing an insulated glazing alike mechanism preventing fogging.
If you want prevention in the first place to free yourself from the hassle, you could just buy yourself one that features a high-performance venting and anti-fog coated lenses.
