How to prevent fog and rain in helmet lenses?

Apply glass water to the helmet lenses.

It can be anti-fog and rain-proof.

The fogging on the helmet lenses is caused by "cold on the outside and heat on the inside."

caused by temperature differences. The surface of the glass wiped with glass water forms a protective layer of monomolecules. This protective film prevents the formation of fog droplets and ensures that the windshield is crystal clear and has a clear view.

Helmet lenses anti-fog, rainproof methods are as follows:

Original anti-fog treatment.

Some helmet lenses have been coated with an anti-fog coating on the inner layer of the lens when they leave the factory, and the anti-fog effect is still good after testing, but after the moisture accumulates to a certain extent, although the lens does not fog up, it will make the vision of the lens become slightly distorted.

2.Slobber. Many people often use saliva to apply to the inside of their goggles when swimming to prevent fogging, but on the lenses of helmets, the effect is not obvious.

And because the saliva applied is not uniform, there are a lot of irregular lines on the lenses, and this method is barely able to try it in an emergency, but it is not suitable for regular use.

3.Neutral detergent.

Using a neutral detergent to treat the lenses, using a small amount and evenly applying to the inside of the lens, can indeed achieve the effect of anti-fogging, but when the moisture level is too high, the anti-fog effect will be greatly reduced, so this method is barely okay.

4.Anti-fogging agent treatment.

The spray anti-fog agent is more professional than the detergent and saliva, and the actual effect is indeed more obvious, but it takes a lot of effort to operate, so unless you know for sure that it will rain, this method is indeed a bit inconvenient.

5.Anti-fog patches.

The anti-fog patch is more expensive than the general one, but the anti-fog effect is immediate, and the anti-fog patch also has an automatic color-changing and anti-glare function, but the inner layer of this lens needs to be kept dry, otherwise the anti-fog effect will be greatly reduced, but the anti-fog patch cannot be reused after being used once, which is a small pity.

I bought a domestic helmet of more than 100 yuan, and the anti-fog lenses are no fog at all, which is magical. View the original post

The difference between helmet anti-fog and non-anti-fog, if the helmet is anti-fog, if it encounters rainy or foggy weather, it will play an anti-fog role and can be ridden normally. However, helmets without anti-fog function cannot play an anti-fog role in rainy or foggy weather, and the eyes will blur and affect riding.

Helmets are more practical with anti-fogging. Because the helmet strap can resist the wind, for example, the fog is relatively large in winter, if it is not foggy, the fog will be brought on, and the vision will be blurred. Then the anti-fog one will be more practical.

Can the anti-fog helmet really be anti-fog, some of the helmet lenses are originally anti-fog, but due to the particularity of his shape and material, the anti-fog treatment of the helmet itself lenses.

At the beginning, the anti-fog is better, but it is not resistant to aging, with daily use, cleaning, it will gradually fail, generally about 3 months - 1 year, depending on the process of each brand. Lai Yan headlines.

Professional anti-fogging, or need to use durable anti-fog patches, this kind of anti-fog patches because of the anti-fog treatment process is different, the firmness of the anti-fog coating is much better than the helmet's own anti-fog windshield treatment. Therefore, the use time is also longer, and some even the molecules of the original material are anti-fogging, and the made sheet can of course be anti-fog for a long time.

Anti-fog helmets are anti-foggy. The anti-fog helmet uses a professional anti-fog patch, which is much firmer than the helmet's own anti-fog windshield due to the different anti-fog treatment process. Therefore, the use time is also longer, and some even the molecules of the original material are anti-fogging, and the made sheet can be anti-fog for a long time.

Apply glass water to the helmet lenses to prevent fog and rain.

Fogging on the helmet lenses is caused by a temperature difference of "cold on the outside and hot on the inside". The surface of the glass wiped with glass water forms a protective layer of monomolecules. This protective ignition film prevents the formation of fog droplets and ensures that the windshield is crystal clear and has a clear view.

There are several ways to prevent fogging in helmets:

1. Treat the lenses, and soak the lenses in the potion used for fiber modification, so that the water vapor cannot condense on the lenses. This is the most costly.

2. Add a large nose mask to the inner part of the helmet to prevent water vapor from spraying into the lenses, and the water vapor will be pumped out to the outside of the helmet by the bionic air pressure difference during riding. This method is much cheaper and simplest than the first method.

3. Spray a layer of anti-fogging agent on the helmet lens, and the effect is not bad, but it is more troublesome to spray frequently.

4. Use design means to control the direction of air flow in the helmet, and then quickly extract the water vapor in the helmet to reduce the humidity in the helmet when riding in winter, so as to achieve the effect of anti-fogging.

Among the above methods, the first cost is the highest, and the fourth has the highest requirements for the design level of the manufacturer, because thermal insulation and ventilation in winter are relatively contradictory, and it is more difficult to achieve a balance point so that the helmet is both insulated and not wet. This highlights the technical strength and design level of the manufacturer.
