Before the epidemic, cheapest eyeglasses online fogging would only appear in winter when going out, hot pot opening, etc., and now because of long-term wearing masks, the fogging time has been extended to all year round...

There are also a lot of anti-fog products on the market, which can return the glasses party a clear world?

Let's start with a happy little conclusion: most of the regular anti-fog products for glasses are effective!

The reason for fog is that the temperature difference causes water vapor to liquefy and form tiny water droplets on the surface of the lens when it is cold, and the uneven distribution of water droplets causes fog.

Anti-fogging products work in a similar way - the anti-fogging agent is applied to the surface of the lens to form a layer of hydrophilic protective film, which is an anti-fogging film. This film will reduce the tension between the lens and the water droplets, so that the tiny water droplets can be better spread on the surface of the lens, forming a more uniform film of water, so that the lens will not have a layer of fog.

Anti-fog glasses cloth, spray, wet wipes

All useful

There are three main types of anti-fog products on the market - anti-fog eyewear, anti-fog spray, and disposable anti-fog cleaning wipes.

Anti-fogging glasses cloth stores the anti-fogging agent in the internal water-locking fabric layer, and the anti-fogging agent will be applied to the lens surface when wiping the lens. The dry pile layer on the surface plays the role of wiping.

There is also a dry anti-fog mirror cloth on the market, which combines related materials into the mirror cloth fiber, which is relatively not volatile and can be used for a longer time, but also needs to be stored in a sealed bag to extend the use time.

Because the antifogging agent is stored in the mirror cloth, the mirror cloth should be stored in a sealed bag to avoid liquid volatilization and failure. It can't be washed, or the anti-fog ingredients in it will be washed away, and it will be useless.

The anti-fog spray, the main ingredients and anti-fog glasses cloth built-in ingredients are similar, may also increase surfactants, disinfectants, etc., so as to play a better role in lens surface cleaning.

Disposable anti-fog cleaning wipes, and the core ingredients of the above two products are essentially no different, the same anti-fogging agent, disinfectant, surfactant. At the same time, it can also play the role of cleaning the lens.

In terms of anti-fog duration, anti-fog can generally be guaranteed for a whole day. However, the specific effect may also be affected by the number of wiping, measurement, uniform degree of application, temperature and humidity, and the cleanliness of the lens.

Spray and wipes, because the anti-fogging agent applied to the lens is a little more, so the effect will be better than cloth.

In terms of use, disposable mirror paper has both cleaning and anti-fog effects, and it is the most convenient to wipe. However, because there is more solution on the surface of the mirror paper, there will be liquid residue on the surface of the lens after wiping, and it takes time to volatilize.

Before using any anti-fog products on the lens, it is recommended to clean the lens first to avoid dust scratches when wiping the anti-fog products directly, and to ensure that the anti-fog effect is not compromised.

Also, don't buy too many of these anti-fog products at a time, because the active ingredients are not good to use after volatilizationv
