You always end up with the same methods. Turns out there are all types of ways to counteract this frustrating fog, from simple hacks to clever tweaks that block the hot air. Check out our comprehensive list for every solution imaginable.
Why do face masks fog up our glasses in the first place? The science is simple. Hot, moist breath from your mouth is warmer than the air outside, creating condensation on your specs. Often if your face mask is ill-fitting or baggy, it leaves gaps between the fabric and your face, allowing that hot air to escape. The goal of how to stop glasses from fogging is to prevent any air from escaping from the top of your mask. But how do you do that? A well-fitting mask should sit directly on the tops of the nose and cheeks without any part of the fabric gapping.
If your mask is too big, here are some easy solutions:. By pulling up your face mask, you can comfortably place your glasses on top of your mask. Still foggy?

Slicing a raw potato and rubbing it on the lenses will leave a starchy coating that resists moisture, just like glycerin does.

Car windows mist up when the temperature of the outside air is cooler than that on the inside, and this typically happens in cooler and damper periods of the year. Headlights are no different: a film of condensation builds up on the inside of the lens due to precisely the same climatic conditions.
Experts call it fogging. There is a similar — but unfortunately less effective — way of alleviating the headlight problem. Because the warmth emitted by the headlight lamps has a similar defogging effect to the warm air from the fan, driving with the lights on helps to avoid build-up of condensation.
Modern light sources, however, generate less heat than halogen lamps and incandescent lights: Xenon headlights, for example, have a greater tendency to fog up than those using halogen lamps. The problem of fogging is one that headlight designers have grappled with for years.
A compounding factor is that headlights are becoming increasingly larger and therefore contain more interior air. This air heats up while the car is being driven — due to the warmth of the lamps and the heat from the engine.
Almost all modern headlights have a ventilation system that prevents a build-up of pressure by displacing this hot air, and this system is carefully designed to allow no direct ingress of water into the headlight housing.
However, in line with normal physical laws, air from outside is sucked back into the headlight interior when the inside air cools down again. If this outside air is humid, due to the prevailing weather conditions, condensation forms on the inside of the cover lens.
Fogging disappears of its own accord after the headlights are switched on. Designers seek to accelerate this demisting process by diverting the residual heat from lamps or control gear through the headlight housing.
Despite all these efforts, not enough dry air is able to reach the farthest corners of the housing, and this is where condensation persists the longest.
How long it actually takes until the lens is completely clear depends on the current weather conditions and level of humidity. When a vehicle is stationary, it takes even longer — and warmer weather — before the condensation finally disappears. In many cases, daytime running lights have made the fogging situation even worse. When trying to prevent fogging, it therefore makes sense to drive with your low beam headlights on instead of your daytime running light s, as more drivers tend to do in the fall and winter seasons anyway.

Off-road and highway driving place different requirements on headlights. And drivers of farm vehicles, for example, also have special needs.

Fogging occurs when atmospheric humidity close to a transparent surface condenses.
This is as a result of the difference in the temperature of the surface and the surrounding air. As the surface tries to balance between the two temperatures, heat energy is released. The water molecules become gas and the energy within it decreases to form small water droplets on the surface. These water droplets are referred to as fog. To clear this up, the anti-fog coating is used.
Luckily, water molecules are attracted to glass, and if this attraction should be enhanced, the surface tension which draws its molecules together to form droplets can be overcome.
The mechanism of anti-fog technology depends on this concept to overcome the surface tension so that the water spreads out in sheets.
The coating needs to be constantly exposed to UV light which is what charges them and as such, they do not function well in low light or in the dark. Fogging is annoying, especially for people who use recommended lenses. When the atmospheric moisture condenses and your glasses fog up, it leaves you virtually blind and this can be dangerous if you drive on a highway street in winter wearing your lenses.
