I have been wrong for many years!It turns out that glasses cloth cannot be wiped at all

A breath on the lens, and then wiped the lenses with glasses cloth or paper towels ... This string of action believes that friends who wear glasses can not be familiar with it, but is this operation that we are accustomed to it really correct?

Wipe glasses with glasses cloth easy to wear lenses

Many people think that the piece of cloth sent when buying glasses is the cloth of the glasses. In fact, it is only to protect glasses and avoid bumps from glasses and glasses boxes. In addition, most of the glasses on the market are not delicate enough, and it is easy to save dust and small foreign objects on the cloth and lens. If you rub it with glasses directly, it is equivalent to rubbing the lens with small particles.

The dust or oil of the lens is actually mostly the fat on our eyelashes, the keratin on the face, and the small gravel in the air. Especially gravel, although they look weak, they are actually very hard for lenses and coating. If you wipe the glasses with glasses on the glasses left, the more wipe the more severe, the more serious, and the lens will eventually make the lens "scarred".

Since the glasses cloth is not used to rub the lens, how do you do the cleaning and maintenance of the glasses in daily life? The simplest and most common method is to clean the glasses with water. The correct steps are as follows:

The first step is to fold the mirror arm and use smaller water to rinse the dust and dirt in various parts of the glasses. In particular, don't forget to turn the corner. It is easier to hide dirt here.

In the second step, the cleaning solution (preferably neutral cleaning liquid) is evenly covered with the front and opposite of the glasses. If you use a cleaner, spray it directly; Apply it on the surface of the lens after the foam, and then wash it off with water.

The third step is to use a softer paper towel to dry the water droplets on the lens, and finally put it in the glasses box.

It should be noted that during the washing process, do not wash with hot water, because the membrane layer on the surface of the lens is exposed to hot water (such as 40 to 60 degrees Celsius), which may be hot Put the glasses in a strong sunlight. When using a paper towel to suck the water on the lens, remember not to rub it back and forth hard, otherwise over time, horizontal or vertical scratches will appear.

Although we look at the surface of the lens, although the surface is transparent, its surface is actually distributed with coating with multi -layer different uses, which increases light transmittance, increased abrasion resistance, and increases pollution -proof ability. So wiping the glasses is not to wipe the lens on the body, but to wipe the coating attached to the mirror. If the quality of the coating or lens is not good, and the incorrect wipe method, the coating will be damaged and even fall off directly. If you lose the protection of the coating, the lens will be more easily worn.

Do you have to change the lens?

What should I do if the glasses are worn? Can I only change my glasses directly?

We should observe the wear position and degree of glasses. If it is only abrasion around the lens, it does not affect the center of the lens. The glasses can continue to be worn for a period of time. When the degree changes, the lens is replaced; if the wear is very obvious or in the center of the lens, this situation needs to be replaced as soon as possible. Essence

Glasses with scratches for a long time are more likely to increase the degree, especially for teenagers. Through these scratches, light will become chaotic, which not only affects clarity, but also hurts the eyes. We wear glasses to look clearer and protect the eyes. If the glasses are damaged, it will be counterproductive.

In addition, lens injury may cause the lens protection function to be reduced, such as weakening the function of UV prevention, and cannot block harmful light into the eyes. However, the lenses of some glasses themselves are anti -ultraviolet, so the scratches on the surface may not destroy this function.

In summary, for the glasses clan, we should protect the glasses, usually do cleaning the glasses, reduce the damage to the glasses, and extend the life of the glasses. When the lens is spent, you should check it in time and ask the professional doctor to decide whether to change the lens. For friends who do not wear glasses, you should learn to protect your eyes and avoid excessive eyes and cause myopia.
