Anti-fog lenses are necessary in winter
As a senior glasses lover, I have to complain that the weather in my country has experienced spring, summer and autumn in one week, but it has entered winter like a roller coaster before I am ready, but my glasses are not ready yet!
You may wonder what glasses need to be prepared?
That is anti-fog. The biggest phenomenon in winter is the huge temperature difference between indoor and outdoor. The editor found a thin layer of fog on the glass in the first morning after the temperature dropped, so the glasses cannot escape the nightmare of fogging in winter.
Why do lenses fog up?
In a colder environment, the air is obviously drier. When the lens comes into contact with hot air, there is more moisture in the hot air. When it comes into contact with a cold lens, a condensation effect occurs, forming small crystals on the surface of the lens, causing the lens to fog up.
This phenomenon is generally not dangerous, but you have to be careful when opening the car door. Because the air conditioner is usually turned on in the car in summer, it is easy to fog up. In winter, the car windows are closed, and there is also a difference in temperature from the outside. When opening the car door, you need to pay attention to safety.
What should I do if the lens fogs up?
The first thing to do when the lens fogs up is to prevent fogging. Here are some good ways to prevent fogging of the lens.
Anti-fog agent for lenses: After cleaning the lens, spray the anti-fog agent for lenses evenly on the surface of the lens after wiping. It can generally last for 1-2 days.
Anti-fog lens cloth: It is a specially treated lens cloth. Use the anti-fog lens cloth to repeatedly wipe the surface of the lens. The lens cloth needs to be sealed and stored after use to prevent the anti-fog function from evaporating.
Soap or detergent: Dip a little soap or detergent on the lens cloth, and then use the lens cloth to wipe the surface of the lens, which can also prevent fogging.
Anti-fog lenses: There are also special anti-fog lenses for glasses. When fitting glasses, you can directly choose special anti-fog lenses, which are convenient and permanent.
Anti-fog lens recommendation:
There are two types of anti-fog lenses. The first type requires an anti-fog lens cloth to activate the anti-fog factor on the lens. When the anti-fog function on the lens declines, it needs to be activated again with an anti-fog lens cloth; the second type of lens is coated with a hydrophilic anti-fog film, which forms a highly adsorbable, dense, and hydrophilic anti-fog film layer on the surface of the lens, so that the lens can eliminate the problem of fog.
