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!

Glasses have already become a trend item in the fashion circle, not only for myopia. Even now, people who are very short-sighted will choose to wear contact lenses plus a concave shape of glasses, because it can choose a more fashionable style and ensure the clarity of glasses. As for why glasses become a fashion item, it is actually very simple, because it can improve the bug of the face.

In order to better adapt to our face problems, eyeglasses frames also have the choice of round and square frames. When glasses were not promoted to star items in the past, everyone's attitude towards glasses was rejected. The derogatory sense implied by the word "glasses sister" is greatly explained. Now, it is found by the big family that there is moisturizing for facial bones, and the joint effect of lenses and frames is more effective than that of makeup It's convenient and easy to use, so girls with the following five questions may as well try to add a pair of glasses.

Sunken Temple, expanded zygoma

Cheekbone outspread is a problem that needs a lot of effort in cosmetic repair, and we all know that cheekbones are too prominent and easy to grow old, so it's much better for friends with this problem to add a pair of glasses. The lenses on both sides of the glasses form a right angle with the spectacle frame, adding a three-dimensional space, keeping both sides of the cheekbones and the spectacle frame at the same level, and increasing the sun The protuberance of the acupoint makes the face look smoother and much younger.

Square face with wide jaw

How does glasses improve the effect of mandible in eye position? This is a visual problem. Square face will show wide face. At this time, the choice of eyeglass frame is also very important. Instead of square face, we should replace it with round one. Use arc to ease square edges and corners, plus the convex effect of glasses on the face to achieve the visual sense of lengthwise stretching, so that the whole face is less rigid.

The eyelids are weak and the eyes are dull

Qiao Xin is a good example. There are a lot of extra points for the glasses on Qiao Xin's face. She belongs to the type of eyelid myasthenia, so she often feels a kind of insensibility. The glasses can cover the problem and play a certain role in magnifying under the role of the lenses, so it looks better.

Flesh face with broad cheek

In fact, girls with flesh on their faces can try to use glasses to decorate their faces instead of just covering them with hair. Only when their cheeks are wide can they make their faces look big. A pair of glasses on them can disperse the visual sense in the middle area. In addition, the visual divergence of the glasses themselves reflects the effect of visual error.

Wide eye distance and low mountain root

The eye distance is too wide to make the face look large. The nose bracket in the middle of the glasses can narrow the visual sense. Another problem is that the eye distance is relatively low compared with the mountain root. The facial features don't look solid enough. The connection of the nose bracket in the middle of the frame can fake the visual height of the nose bridge, forming a visual dislocation situation, so that the problems between the eyes are well covered It's simpler and more convenient than cosmetic!

UV is an invisible killer,

The eyes are exposed to strong sunlight,

Crystals in the eye can be exposed to too much ultraviolet light

And fiber hardening,

And the damage of ultraviolet to human eyes is cumulative,

It will develop some eye diseases,

Such as cataract, glaucoma, etc.

So what color of lens can protect the eyes most?

1 green lens

Green lens is the representative of pilot series, which can effectively absorb infrared light and 99% ultraviolet light. But green lenses can distort the color of certain scenes. Moreover, its light blocking effect is slightly inferior to that of gray lens, but green is still an excellent protective lens. Green has the function of adjusting eyesight, which is more suitable for students or people with tired eyes.

2 Grey Lenses

The Gray Lens absorbs any chromatogram evenly, so it will darken in case of strong light, but there will be no obvious color difference, showing the true natural feeling, belonging to the neutral color system. It can absorb infrared and 98% ultraviolet. The biggest advantage of gray lens is that the original color of the scene will not be changed by the lens, and the most satisfying thing is that it can effectively reduce the light intensity. Gray can reduce visual fatigue, white-collar workers with more eyes can consider.

3 yellow lens

It can absorb 100% ultraviolet light, and make infrared and 83% visible light penetrate the lens. The biggest feature of the yellow lens is that it absorbs most of the blue light. Because when the sun shines through the atmosphere, it is mainly blue light (which can explain why the sky is blue). After absorbing blue light, the yellow lens can make the natural scenery clearer. Therefore, the yellow lens is often used as a "filter". Yellow is the most sensitive color of visual cells, which can improve the sensitivity of vision. Amblyopia and other poor vision can be preferred.

4 Pink lenses

This is a very common color. It can absorb 95% of the ultraviolet light, and some shorter wavelengths of visible light. In fact, this kind of function is similar to that of ordinary uncolored lens, that is to say, pink lens has no greater protective effect than ordinary lens. But for some people, it's still psychologically helpful because they feel comfortable to wear. There are red and green color blindness or red and green weak person, can choose red lens, it can increase red and green contrast.

5 Brown lenses

This kind of lens absorbs almost the same kind of light as the green lens, but absorbs more blue light than the green lens. Brown lenses cause more color distortion than gray and green lenses, so the satisfaction of ordinary people is also low. But it provides another color choice, and can slightly reduce the blue light halo, making the image clearer.

6 Blue Lens

The beach can wear the sun blue lens, blue can effectively filter out the light blue reflected by the sea water and the sky. Avoid using blue lenses when driving, because it will make us unable to distinguish the color of traffic signals.

In addition to the traditional sunglasses, the so-called "anti radiation, anti blue light, anti fatigue, anti UV" anti blue light glasses have recently become the choice of many people.

The sunlight includes seven bands of "red, orange, yellow, green, blue, indigo and purple". Blue light is one of them, which has relatively high energy.

Blue light is a kind of normal visible light in daily life. The wavelength is about 400 nm, which just falls in the center of the eye, that is, the fovea of the macula. And this part itself is sensitive to strong light, which is mainly composed of optic vertebra cells. If it is stimulated by blue light for a long time, it will suffer some damage.

For people's concerns about the harm of blue light to eyesight, anti blue light glasses have no significant effect on eyesight protection. To protect eyesight, we should pay attention to the health eye, try not to use electronic products for a long time, and do not use the eye for a long time.
