1. Some people say that the degree can't be matched too deep, otherwise it will be worn deeper and deeper?

Answer: this statement is incorrect. The degree is not enough. The patient will squint when looking far away, causing ciliary muscle contraction (to be adjusted), leading to eye fatigue, which on the contrary makes the degree easier to deepen.

2. Then I won't be old? (nearsightedness now)

A: old flowers are a physiological phenomenon. Everyone can. This is because the function of ciliary muscle declines with age, which makes it difficult to see near (especially to read and write). Therefore, it is called Laohua, but the myopic or the person with good examples should be hesitant. If the myopia degree is shallow, it can be washed away with the old flowers, so when you look near, you can take off the reduced degree of the height number, and you can see the distance unchanged.

3. After glasses match, whether should wear often?

A: Generally speaking, if the degree is relatively shallow - 1.00-2.00, you can not often wear it when you look close to it. In this way, you don't need to increase the adjustment of your eyes. If you read more than - 3.00ds, you need to wear it no matter whether you look near or far. If you don't wear it, you can see the object blurred, and the adjustment will be deepened, leading to the deepening of fatigue.

4. Why do some people wear sunglasses with larger radian to appear giddy?

A: Yes, some people have this kind of situation, mainly because of the sensitivity of the eyes and the large radian of the lens. After assembly, there may be a certain prism effect, so there is dizziness.

5. Why are the new glasses uncomfortable at first?

Answer: there are many reasons. A. the degree may be different. B. the angle has changed. Old glasses have formed a bad habit of wearing for a long time due to deformation and damage. C. The old glasses have to adapt to the correct angle. C. The old glasses have blurred the lenses and blurred the objects due to wear. However, the new glasses suddenly feel much brighter due to clarity, which leads to visual impact, so they don't feel it Yes.

6. I have cataracts. Can I have glasses?

A: first of all, do you want to make sure that you are in the early stage or in the middle and late stage? If it is early, most of the results are good, but if it is in the middle and late stage, the effect is not obvious. It is recommended to wear glasses three months after operation.

7. Does dot have pseudomyopia? What is pseudomyopia?

A: it can't be completely said that the so-called pseudomyopia is due to the continuous contraction of ciliary muscle. Over regulation leads to spasm of regulation and increase of the refractive power of the eyes, resulting in myopia of both eyes and decrease of vision. Eyesight fatigue phenomenon, as long as relax adjustment, see more distance, more exercise, you can return to normal.

8. When children read and write, is it better to use incandescent lamp or fluorescent lamp?

Answer: in principle, incandescent lamp is good. For a small table lamp with wattage between 25W and 40W, the light comes from the left side. It's better not to direct your eyes. The light of fluorescent lamp is not stable.

9. Are presbyopic glasses worn deeper and deeper?

A: it can't be said that without wearing the presbyopic glasses, they will get deeper and deeper. This is a physiological phenomenon and a manifestation of the decline of our regulatory function. Everyone is the same.

10. How can I feel something flying around like a mosquito sometimes?

Answer: this kind of phenomenon may be floater mosquito disease. If it happens only occasionally, it will not increase. It may be physiological. Often, it may be pathological. It is vitreous turbidity caused by intraocular disease, hemorrhage or degeneration. You need to go to the hospital.

It's said that the world of myopia is like this: six parents don't recognize each other 20 meters away, men and women don't recognize each other 50 meters away, people and animals don't distinguish 100 meters away; our world is pure, we are not indifferent, just a little fuzzy.

So the existence of glasses is really the most useful invention. Without glasses, myopia can't imagine the world at all, or only rely on imagination

So ancient people did not have glasses, if they were short-sighted, how should they live? There is a saying that the Chinese invented glasses 2000 years ago, but this is not accurate. It should be that our country has discovered the lens made of crystal and gem very early. Crystal has the function of amplification.

But glasses are made of glass. Glass is originally foreign. Therefore, glasses should be used by foreigners as a tool to correct vision.

The inventor of glasses, sovino de GRI Amadi, was an inventor in Florence. It was probably in the early 13th century. At that time, the technology of glass was very mature, so the conditions for the invention of glasses were basically met. The scientist discovered the secret of convex lens and concave lens. After discovering the secret, he began to study how to turn the glass into a curved shape and how to adjust the angle. Finally, the glasses were made.

However, as glasses did not become popular at that time, it is estimated that there were too few myopic people at that time, or the technology of making glasses was not good enough, there were too many impurities, and the curve of glasses was not very good. Although not widely circulated, there are glasses at last.

About five hundred years later, in the middle and late 13th century, the glasses came to Franklin. As we all know, this scientist invented lightning rod, odometer, forest stove, glass organ and so on. Franklin read a lot and knew a lot. In his 60s, his eyesight dropped a lot. He was probably presbyopia. He could see far away and near.

But he always has to work and write things, so he invented a pair of glasses, called bifocal glasses, which the elderly all know. It solves the problem of seeing far and near at the same time on a pair of glasses by adding a positive lens degree to the lower part of the glasses. It is a kind of presbyopia glasses.

There is also a saying that glasses were invented by British philosopher bacon. Once he took a walk, he found a lot of water droplets on the spider web. He found that when he looked at the leaves through the water drops, the meridians on the veins of the leaves were enlarged a lot, and even the fine hairs on the leaves could be seen.

After discovering this phenomenon, bacon was very excited. He found a glass ball and looked at the text through the glass ball. It was a bit unclear. Later, he cut a piece of glass and enlarged the text. The experiment was successful. Finally, he made glasses. This story has also been written into the textbook, and the story of Bacon's invention of glasses has been sung everywhere. Presumably, this invention story can also inspire many children's interest in science.

Although there is a long history, many things can not be verified clearly. Moreover, the process of invention is to step by step and inspire each other. But it can be confirmed that the first myopia glasses appeared in Europe in the 13th century.

Another way of saying is that in 1352, in an Italian painting, there was a figure painting. The person in the painting was an old missionary. He was reading a book and reading a manuscript with a pair of glasses on his nose. Moreover, it was a famous painting. Judging from this painting, it is said that the glasses were invented by armadi of Italy and the missionaries in the painting, which is also believed by many people, but it was already the 14th century at that time!

In a word, no matter which invention, it has great significance. Today, with the development of glasses, in addition to frame glasses, all kinds of beautiful pupils are also the favorite of many young people, but Xiaobian still wants to say that if the degree of myopia is not very large, unless you go to the railway station, airport and other places, you should not wear glasses every day, especially beautiful pupils, which will really aggravate the degree, and you can't do without glasses in the future!

Progressive multifocal is the French Bernard Maitenaz first applied the principle of progressive multifocal lens to glasses in 1959 after eight years of research. Between the high beam area and the near use area of the same lens, the far use area and the near use area can be organically connected from the far use area to the near use area in the way of gradual change of diopter. Therefore, on one lens, the far, medium and short-range stations can be set up at the same time Different luminosity required. The original intention of progressive multifocal lens design is to provide a natural, convenient and comfortable correction method for presbyopia patients. Wearing progressive lenses is like using a camera to take pictures. A pair of glasses can not only see the distance, but also see the near. So we describe progressive lens as "zoom lens". After wearing one pair of glasses, it is equivalent to multiple glasses.

Progressive multifocal lens

The difference between progressive multifocal lens and bifocal lens: grind two different refractive forces on the same lens to become two area lens, which is called bifocal lens or bifocal lens. Although the binocular glasses can see far and near, there are obvious gaps in different areas, unsightly appearance, fuzzy middle distance, need to adapt period, prism jumping phenomenon, going up and down the stairs will be dizzy. The progressive multifocal lens has no obvious spacing, and its appearance is more beautiful and comfortable as the common myopia lens.

bifocal lens

1. Look far:

The upper part of the progressive multifocal mirror is the remote central area, which can let the presbyopic friends see the long-distance vision.

2. Look far and look close middle distance:

There is a distance between the far center and the near center, which is a gradual process from seeing far to seeing near. It changes gradually with the degree of hyperopia and myopia. The longer the middle distance is, the smaller the range of the center area and the near center area is. The shorter the middle distance is, the larger the range of the far center area and the near center area is.

3. Look close:

The lower part of the progressive multifocal mirror is the near center area, which can let the presbyopic friends see the close field of vision.

4. Astigmatic area:

There are astigmatic areas on both sides of the progressive multifocal mirror, and the astigmatic areas are fuzzy areas. The larger the fuzzy area is, the longer and narrower the near middle distance is, the smaller the fuzzy area is, and the wider and shorter the near middle distance is.

5. Add value:

In the process of optometry, the diopter needed to see far should be determined first, that is, the diopter of far use. Again, the diopter needed to see the near is the number of near uses. The absolute value of the difference between the two degrees is the down add light, also known as add. Add is the main parameter of progressive multifocal lens, which must be measured and written clearly. The principle of optometry prescription should be composed of far use degree and add degree, because its value affects the choice of lens. The lower light is the light added on the basis of looking far.

Wearing presbyopia glasses is also very learned. You must have accurate optometry before matching glasses. Otherwise, wearing inappropriate glasses will only backfire and even cover up some eye diseases, such as cataract and diabetes in the eye. Progressive multi focus glasses are customized glasses, which can be customized according to your optometry results, face shape, skin color, hair style, etc. It is easy to wear (only one pair is needed to look far and near, and only one pair is needed to look far, nearsighted, presbyopia and astigmatism); it can control the growth of presbyopia degree (it is not necessary to take it back and forth, and it is comfortable to wear it for a long time); it can not see the age limit (the appearance is the same as the myopia mirror, light and beautiful); it has many functions (discoloration, UV / blue light resistance).
