Anti-fog mirrors are divided into coated anti-fog mirrors and electric anti-fog mirrors. The former is to prevent the formation of fog layer by coating micropores, while the latter is to increase the mirror temperature by electric heating, and the fog quickly evaporates, making it impossible to form fog layer. In addition, there are other types of anti-fog mirrors on the market. The surface of anti-fog mirror is specially treated by extraction, coating or infiltration technology, which improves the surface tension. As long as it is kept clean, water molecules will not condense water mist, but only stay, thus avoiding the trouble of fogging when the temperature difference occurs. The bath water temperature is close to human body temperature, between 35℃ and 40℃, and the surface temperature of bathroom mirror is slightly lower than room temperature. Large temperature difference+humid air after bathing are two necessary conditions for fogging of bathroom mirror. The real anti-fog mirror should be double-layered, with electric heating wires inside. Mirrors can be heated and evaporated as soon as they encounter water vapor, so they are called anti-fog mirrors, which are very expensive. When you buy it in the market, every store calls it an anti-fog mirror, boasting not to be fooled by profiteers. Now profiteers don't even consult.
Advantages: 1, light weight. 2. Non-fragile: the lens is broken, which is not only less fragmented, but also less sharp, which can minimize the damage to the eyeball and face, such as super tough resin lenses. If other brands are anti-fogging, the film plated on the lens has anti-fogging effect and does no harm to the glasses. If the film is not well made, it will affect the refraction and transmission of light and cause harm to the eyes.
It is recommended not to dilute the detergent when smearing, but to wipe it with a dry cloth after smearing. The active ingredients contained in Xijieling can effectively prevent water vapor from condensing on the mirror surface, so it can play an anti-fog role. It is necessary! After taking a bath in winter, ordinary mirrors are blurred by water vapor! Just fog-proof! Anti-fog lens is relatively easy to scratch, because it is a soft film with a hard film on the outer layer, but it is more practical. Anti-fog lens cloth is also effective for ordinary lenses, generally speaking, it can last for a day or two, and the price is not high, so it is very practical.
