Before you understand this, you need to know what are contact lenses?
Before the sixties, except for the earliest hand-held glasses (which we often see in Western movies), people only knew that glasses could only be put on the nose, otherwise they could not be called glasses, who would have thought that later it could be attached to the eyeballs? It wasn't until the introduction of the first soft contact lenses in 1960 that there was a fundamental shift in this concept, and that's when the glasses on the eyeballs were born, followed by the brands we're all familiar with now, such as Dr. Doreen and Haichang.
But most people find it hard to accept the idea of putting something on their eyeballs because it's definitely uncomfortable, and safety is also a factor we consider more, but it's really beautiful and convenient, and it's based on those two things that people are slowly starting to accept after two or three decades of spreading the word.
Now, looking back, not only are more and more people wearing them, but their function has gone beyond restoring eyesight. Many young people, even if the vision of both eyes are normal, but also still wear it every day, because it is no longer simply glasses, the appearance has become colorful, and I do not know who also gave it a nice name called "pupil", as if wearing it is equal to the beauty of the same journey, wear it, you can make you look more beautiful.
Invisible masks are also a reason with contact lenses, but it is no longer the mouth and nose full cover up, but a middle with a filter into the nostrils of the small nose plugs, by closing the mouth only nasal breathing, so that the air through the filter after filtering into the lungs, so as to achieve the purification of the air to protect the respiratory system purpose. It is small and soft, into the nostrils, not around to look closely, stand far away is not easy to find, so it is called "invisible" mask.
◆ Invisible masks, although small, but the filtering effect?
The filtration effect depends on how good the filter is in the invisible mask. Good filter, not only can filter PM2.5, at the same time it can filter dust, pollen, flotsam, car exhaust, second-hand smoke, and so on, and even rhinitis and respiratory allergies have a good protective effect. But there is one thing we must pay attention to when choosing, is the invisible mask must not choose the activated carbon filter, because the activated carbon is only on the toxicity and odor adsorption effect, and not be able to filter PM2.5, and the most critical is the invisible mask is put into the nostrils, inhalation needs to be closed tightly mouth only with the nose to breathe, which was originally the need for the mouth and nose and the pressure of the nose, and put the pressure of the airflow when inhaling. The pressure of the airflow will also increase when inhaling, if the filter layer is activated carbon, it is easy to inhale the activated carbon particles directly into the lungs during the inhalation process causing secondary damage. Therefore, I personally do not recommend the use of activated carbon as a stealth mask filter material, if consumers just want to filter the flavor, it is best to choose a conventional activated carbon mask, because that way of breathing is the mouth and nose, and the nostrils away from the activated carbon layer is farther away from the nostrils, not like the stealth mask directly into the nostrils, so only from the filtering of the flavor of the level of the conventional activated carbon mask is more secure.
◆ Is breathing as smooth as with a conventional mask after wearing an invisible mask?
Strictly speaking, the breathing of the invisible mask is not as smooth as the conventional mask. Because the regular mask is the mouth and nose and used to breathe, while the invisible mask can only be used with the nose, otherwise the role of the mask is lost. But whether you use the nose or nose and mouth, as long as you can ensure the normal supply of oxygen and filter out the harmful substances in the air, their effect is the same. I remember reading a report that a professional doctor said that N95 masks can not be worn normally for more than 15 minutes, otherwise it will have an effect on the body. What does it mean? It means that wearing it you have difficulty breathing! Use people will say, I put on after breathing is not difficult ah, quite smooth, that can only mean that your mask filtration effect is not up to standard. Normal filtration effect is the filter material in the equipment air through the test results, that is closed, the reality is that there are a few people wearing masks and face is 100% closed? Once the seal is not tight, the filtration effect will be greatly reduced, no matter how good its original filtration effect, if you can still breathe well, it can only mean that the leakage of air. Anyone with a good seal should have trouble breathing or the filtration will suffer.
The filter material is good or bad at the same time determines the filtration effect. Protection and permeability which are two contradictory theories, not at the same time to reach the top, the better the protection, the worse the permeability, and vice versa. This is common sense, do not listen to others to fool his product protection and good breathable and strong, it is impossible. Good products are just in the middle of these two theories to find a balance, see you more important to its protective, or more important to its breathability, and then choose the appropriate product can be. Some products in order to increase the breathability, to give consumers a comfortable feeling to wear, has been the filter material is so thin that almost lost the filtering effect, but many consumers who do not know the truth to buy back has been good, very breathable, in fact, when it understands the truth, it will not be so naive that, just a lot of businessmen are not willing to tell consumers about this common sense. Good invisible mask, wear up breathing can never be very smooth, should obviously feel a slight breathing resistance, but adapt to it is still acceptable, this state is the most ideal. So that the movement of the crowd is not suitable for wearing an invisible mask, because they need a lot of oxygen, must ensure that they can breathe a lot.
◆ What material is good for the invisible mask? How to choose?
Currently recognized as a better material for invisible masks is food-grade silicone. Because this material is the most healthy, non-toxic and tasteless, high and low temperature resistance, can withstand -60 ℃ ~ 200 ℃ temperature, soft, elasticity, resistance to twisting and deformation, not yellow, no color fading, long placed in the water, no scale, no odor, commonly used in baby pacifiers, baby teething device, food molds, human organs cloning and so on. But there are some manufacturers with plastic most invisible mask material, because the transparency of the plastic is good, the performance of the product details are better than food-grade silicone, but the only bad thing is that it is not food-grade silicone environmental protection and health. However, the only bad thing is that it is not as environmentally friendly and healthy as food-grade silicone. Consumers seldom have the opportunity to understand this, and they only decide to buy based on the appearance of the product and the manufacturer's introduction. But with the growing popularity of invisible masks and consumer awareness of the perfect, I believe this situation is slowly improving.
◆ Is it comfortable to wear an invisible mask?
When you wear an invisible mask, you will definitely feel uncomfortable. After all, the nostrils are always stuffed with something, but adapting to a period of time, as short as a moment, as long as a day or two, will be adapted to. It's like contact lenses, it's just as uncomfortable when you start wearing them. As the saying goes, you can't rub sand in your eyes, let alone sticking something in your eyeballs, it takes time to get used to it. Some masks will have a very short adaptation time, some people just put it on and adapt, feel nothing uncomfortable. The key factor affecting the comfort or discomfort, the most response is that consumers feel that it is not breathable, suffocating and difficult to breathe. Therefore, some manufacturers make the filter layer is very thin, almost all lose the filtering effect, so that consumers feel breathable on the line, first get a good review again. Do not know, this practice, although increased product sales, but the harm is the health of consumers. A good invisible mask is supposed to find an optimal balance between breathing smoothness and filtration effect, both breathing resistance can also maintain normal breathing at the same time can also achieve a better filtration effect.
◆ Is it better to have a regular mask or an invisible mask?
This question is as difficult to answer as asking whether regular glasses or contact lenses are better.
The two types of masks are worn in different ways, but the purpose is the same: to filter the air and protect the body.
Regular masks have a long history, and the first people in the world to use them were actually our people. In Mark Polo's travels there is a record: in the Yuan Dynasty palace, "offer food people, all with a silk cloth over the mouth and nose, so that their breath does not touch the food and drink". Meaning is to wait for the emperor Kublai Lie diet of the palace people, the mouth and nose are covered with a piece of beautifully woven silk scarf, a inquire about the original so as not to let their own breath and spittle touched on the meal to ensure that the emperor's diet of cleanliness. See, the early most careful not what foreigners, but we Chinese! So this Polo brother returned to his country on this matter into his "Marco Polo Travels".
By 1897, a German doctor, Dr. Ledecky, opened a private practice in Hamburg. He believed that infections were caused by doctors breathing and talking during surgery. So, he used gauze to cover the nose and mouth after surgery, and really make the wound infection rate greatly reduced, and then the mask spread. This raised people's awareness of the role of masks. However, at that time, the mask is just a few layers of gauze, back and forth to the nose, mouth, beard wrapped up, very simple, very uncomfortable. Later, Leducci let the gauze cut into a rectangle, between the two layers of gauze set up a box-shaped wire bracket, and then make a band tied to the back of the head. Thus the mask took its original shape.
In 1899, the French doctor Micky sewed a multi-layer gauze mask; and changed to a free knot method, with a ring band hooked on the ears. 19th century, the French scientist Pasteur founded the modern bacterial (microbial) doctrine, so that people's view of the mask for a new. Florence Nightingale, the mother of nursing, once said that air, like water, gets dirty. If you wear a mask, you can potentially keep germs out of the sandy cloth layer, not allowing the bad stuff to sneak in and harm people.
And then later, every occasion of bad air will be wearing a mask to prevent, the weather is cold, the mask will also be thickened, to play the purpose of the cold.
The use of masks to deal with the haze is only emerging from the last two years, but also people's self-protection helpless. Masks have also improved greatly from shape to function. With the emergence of the word haze, there is also the emergence of invisible masks. China's earliest research and development of invisible masks is an enterprise in Zibo, Shandong Province, because the product does okay, after being imitated by many people, so the market appeared a lot of brands, the quality is also good and bad, need to be carefully screened when consumers buy.
Concealed masks on traditional masks, like contact lenses on traditional glasses, it is a form of leap, but it is not possible to completely replace each other, each have their own living space and consumer groups.
For example, the medical industry, the catering industry, it is necessary to use conventional masks, because not only the need to filter the air, but also to stop the production of droplets. Invisible masks in the filtering of air at the same time, more prominent embodiment of the beauty and convenience. Because there are many occasions you can not wear conventional masks, such as meetings, speeches, receptions, performances, outdoor duty and many work nature of the occasion decided to require that can not wear a mask, but the increasing air pollution today, do not wear a mask will cause great harm to the body. The invisible mask is the perfect solution to this problem. Wearing it, no longer need to worry about the harm of dirty air on the body. Moreover, ladies often happen to wear masks to make up splintered, masks rubbed on the lipstick thing will never happen again. In winter, the eyeglasses family no longer need to worry about wearing a mask after the lens is full of water mist can not see anything. Even at dinner time do not need to take off. In short, there are many highlights! Especially now, the sky flakes, the weather is getting hot day by day, if you always buckle a big mask, so that the face and cheeks everywhere is sticky sweat, summer will even cover the heat rash, can take off the mask and can not filter the air, at this time, the advantages of the invisible masks stand out, it will be the right choice for you!
Knowing all this, I believe you have some knowledge of what is going on with the invisible mask, right?
I have the honor of also distributing invisible masks, so there is some understanding of this, such as you are interested in my treasure pad store "Green Man's Manor" to see.
