Essilor, Zeiss, TAG Heuer, Seiko, Kemi, Rodonstode are all very good. China's Gusu (Suzhou) is the birthplace of glasses in China, and the production of glasses in Suzhou not only has a long history, but also plays a great role in promoting the development of China's glasses industry. In the early years of Chongzhen in the Ming Dynasty (1628 AD), there was an outstanding technician in the history of Suzhou glasses, named Sun Yunqiu, the word Wenyu, and the word Sibin, originally from Wujiang.
He was diligent and studious since he was a child, and at that time he saw that people with poor eyesight were in pain, but "single-vision" mirrors and the like were inconvenient to use. So he developed a lens that could be worn on glasses. After repeated experiments, he used mechanical principles to invent and create a lens grinding machine - a gyroscope.
This kind of puller, which is the so-called orange processed by the classical method, is rotated by foot, using ore sand, white mud, brick ash, etc. as abrasives or polishing materials, and grinding the lens into a convex and concave lens to meet the needs of eye refraction. Finally, he mastered the grinding technique and used natural crystal stone to polish the lenses. At the same time, he mastered the technology of "optometry", developed presbyopia, myopia, farsightedness and other varieties and lenses of various luminosities according to people's age and different vision, and compiled a set of original optometry methods of "eye to mirror" to check the eye.
In this way, you can match glasses with your eyes, the effect is not bad at all, and it is more convenient and comfortable to wear on the face, so as to meet the needs of everyone's eyesight, which is the beginning of independent optometry glasses in China. Later, Sun Yunqiu invented and developed optical lenses for different purposes, including dozens of kinds of flower glasses, mandarin duck mirrors, magnifying glasses, multi-faceted mirrors, and illusion mirrors. Since then, the glasses made by Sun Yunqiu have become famous all over the world.
It is a pity that such a promising technical talent died of illness at the age of 33, but he left behind a scientific and technological work called "Mirror History", which played an immeasurable role in promoting the manufacturing technology of glasses in later generations. Following Sun Yunqiu, during the Qianlong and Jiaqing periods of the Qing Dynasty, Suzhou produced another talent who made glasses, named Chu Sanshan. He further developed the technique of making glasses, which was quite influential.
Due to the emergence of two outstanding technical talents in Suzhou, Sun Yunqiu and Chu Sanshan, which promoted the formation and development of Suzhou's glasses industry at that time. In 1735, there were workshops in Suzhou specializing in the production of spectacles. By the time of the Kangxi Dynasty of the Qing Dynasty, the production and sales of glasses had flourished in Beijing, Shanghai, Suzhou, Tianjin, Guangzhou and other places.
Eyewear has become a specialized commodity.

Good glasses brands include Dr. Glasses, Baodao Glasses, etc.
Glasses are simple optical devices made to correct vision or protect the eyes, consisting of lenses and frames. Spectacles were invented in Italy at the end of the 13th century. At that time, the glasses could only be said to be magnifying glasses, and they were only held in their hands when they were reading.
A pair of spectacle frames is usually composed of the main parts such as the rim, nose pad, stump head and temples, in addition to the above parts, there are also foot covers, leaf support screws, hinge screws, etc.
The lenses used now are basically resin material lenses, and the design of the lenses is basically aspherical design, the selected lens is the aspherical lens of resin material, the aspherical lens has a characteristic, the power of the optical center is a little higher than the periphery, which also means that if the frame is too large, the interpupillary distance is too small, the greater the processing of the center of the center, in addition to the thickness of the edge, not only can not effectively use the central advantage of the optical area, but the surrounding will interfere with the vision of the central area.
Massage into the eyes. If there is discomfort such as dry eyes, you can use your hands to massage and rub the ** tissues of the eye area, which is conducive to regulating the blood circulation of the eyes, and can relax the cell tissues of the eyes in time, which is conducive to alleviating the occurrence of dry eyes and achieving the purpose of protecting the eyes.

There are many brands of glasses, and the bad ones also vary depending on the brand, material, style and other factors. As far as brands are concerned, the quality of glasses from brands such as Sketch, Meishilu, Ray-Ban, Oumeijia, and Zeiss on the market is better. Of course, the quality of glasses is not only about the brand, but also about the material, processing technology and fit.
As far as I know, glasses, resin, PC and other materials are more common at present. Among these materials, resin is the one commonly used in modern times because it is lighter, resistant to falls and wear, and less prone to breakage. In terms of processing technology, the more common processing methods in modern times include monolithic molding and manual adjustment, the monolithic molding process is more accurate, and the processed glasses are more refined.
In terms of fit, you can go to a professional optical store to get a pair of glasses that suits you, which can better prevent vision problems.
In my opinion, it is not necessary to choose a big brand for glasses, and some small brands may have more innovative designs and processes. Therefore, when buying glasses, in addition to looking at the brand, you can also refer to the material, processing technology, adaptability and other factors to choose the right glasses for yourself.

Computerized optometry should not be used as a basis for spectacle dispensing. The machine used for this kind of refraction is an instrument that combines optics, electronics, and mechanics, and its principle is basically the same as that of retinal imaging. In addition, the infrared red light source and automatic fog vision device are used to achieve the purpose of relaxing the eyeballs.
It is easy to operate and fast, and it is a major advancement in optometry technology.
