For people who wear discount prescription glasses, it is easy to spend glasses for a long time, breathe on the lens, and then wipe the glasses with a glass cloth or tissue, this action we are all too familiar with.

But over time, friends who wear glasses will find a problem, sometimes wipe glasses, there are often some places are very fuzzy, and how to wipe is not clean. On closer inspection, it was not dirty at all, but there were many small scratches on it. With glasses cloth more and more flower, because of poor quality or daily operation wrong?

Where did the scars on the glasses come from?

Many people think that the cloth that they buy glasses with is the cloth that cleans them. In fact, its role is just to protect the glasses and avoid the collision between the glasses and the glasses box. In addition, most of the glass cloth material on the market today is not delicate enough, and the cloth and the lens are easy to retain dust and small foreign bodies, if you dry the glass cloth directly, it is equivalent to rubbing the lens with small particles.

The dust or oil of the lens is, in fact, mostly the oil on our eyelashes, the horny skin on the face, the small sand in the air and the dander on the head. Grit, in particular, although they look tiny, is actually very hard for lenses and coatings. At this time dry wipe glasses, the more wipe the more wear, the more wear the more wipe is not clean. The end result is damage to both glasses and lenses.

In addition, when the lens is put back into the mirror box, it is also easy to be scratched by the edge of the mirror box. Rubbing the lens back and forth while cleaning the glasses can also cause damage over time. If the lens is accidentally dropped, rubbed against the rough ground, or flat sliding the lens when picked up, it will cause scratches.

Since the glasses cloth is not used to wipe the lens, then, how to do the cleaning and maintenance of the glasses in daily life? The simplest and most common way to do this is to wash your glasses with water, and the correct steps are as follows:

1. Fold the arm of the lens and use a small stream of water to rinse the dust and dirt from all parts of the glasses, especially the corners (which are more likely to contain dirt).

2. The cleaning solution (preferably neutral cleaning solution) evenly cover the front and back of the glasses, such as using detergent, please spray directly; If you use detergent, dilute it with water on your hands, rub it into a foam, then apply it to the surface of the lens, and rinse it off with clean water.

3. Use a soft paper towel to blot the water off the lens and put it in the glasses case.

It should be noted that during the washing process, do not wash with hot water, because the film layer on the surface of the lens may be burned when it is exposed to hot water with too high a temperature (such as 40-60°C), so it is not recommended to put the glasses in the stronger light summer exposure. When using a paper towel to suck the water on the lens, remember not to rub back and forth forcefully, otherwise over time, there will be horizontal or vertical scratches.

We look at the surface of the lens although it is transparent, but in fact on the surface of the distribution of multiple layers of different purposes of coating, increased light transmission, increased wear resistance, and increased anti-fouling ability and so on. Therefore, wiping glasses is not to wipe the body of the eye lens, but to wipe the coating attached to the mirror. If the quality of the coating or the lens is not good, coupled with incorrect wiping techniques, the coating will be damaged, scratched, and even directly off. If you lose the protection of the coating, the lens will wear out more easily.
