Progressive Multifocal Glasses, What are Progressive Multifocal Glasses?

The reason why it is good to deceive people:

This year, I wanted to recover my eyes again, so I put on my vision glasses to write homework and read books.

But the degree is deeper.

So the cost of Visionstand is just made with ordinary lenses.

The principle of good vision glasses is only that the lower lens power is low, and the upper lens power is also myopia glasses, of course, it is impossible to improve vision!

And Haoshili used the inferior progressive film with a factory price of 60 yuan produced by a small factory in Danyang, Jiangsu, and invited two little broken children to advertise, and sold it at a sky-high price of 1599 yuan.

Wearing progressive multifocal glasses, although it can not completely reduce the refractive error**, but it will not damage the eyes, wearing progressive multifocal glasses, correcting the deficiency of the eyes, improving vision, beneficial to the eyes, beneficial to work and study, will not promote the development of refractive error. As for the development of refractive error in some patients after wearing glasses, a small number of people may be due to the inappropriate glasses, and most of them are closely related to whether myopia patients can use their eyes reasonably. If you still don't take care of your eyes or don't know how to use your eyes scientifically after wearing the right glasses, myopia may still continue to develop, but it is not due to wearing glasses.

Therefore, it is still necessary to pay attention to the reasonable use of eyes after wearing glasses to prevent their development as much as possible.

At present, with the introduction of intelligent zoom technology, progressive multifocal glasses have a wider range of applications, and their role is not only limited to reading glasses, but also has become a new choice for adolescents to prevent and control myopia. Because it has "different focal points on one lens", the upper glazing area is used to see far away, which ensures that the wearer can see far clearly; Looking at the lower light area is easy to see close, so that the wearer can use the eyes at close range for a long time without feeling eye fatigue. The intelligent design ensures that the corresponding degree can be found at each distance from far and near, and truly realizes "the eyes are effortless, the glasses come to focus", and the glasses replace the complex focusing function of the human eye, completely relax the pressure of the ciliary muscle, so that the wearer can easily use the eyes and achieve the purpose of protecting vision.

Juvenile. It should be impossible to reduce the power of adult eyeballs after they are formed.

The difference between defocus glasses and ordinary glasses is: different characteristics, different functions, and different functions.

1. The characteristics are different.

Defocal lenses are made by adding compounds such as titanium oxide to the glass, making the lenses thinner and lighter, and more suitable for making lenses with higher readings, while ordinary lenses are made of optical materials such as glass or resin.

2. The role is different.

The power of the progressive belt in the middle of the defocus lens changes from top to bottom, so the zoom can be adjusted automatically, so it will not hinder you from seeing clearly, far and near. The main raw material of ordinary lenses is optical glass, which has superior optical properties, stable refractive index, high hardness and more wear resistance.

3. The functions are different.

The main function of defocusing lenses is to improve the realism of vision, alleviate visual fatigue, and improve the wearing experience of those who pay before widening. Ordinary lenses are mainly used to improve vision, protect the eyes, and also correct various vision problems, such as astigmatism, myopia, farsightedness, strabismus, etc.
