What is the difference between high-end glasses and cheap glasses?

Is there really such a big quality gap between glasses, and where are the expensive glasses? If you don’t take into account the brand and fashion factors, just from a health point of view, will these cheap glasses have a bad effect on vision?

1.brand

A brand that is widely recognized requires a lot of money to be invested in advertising, which can only be realized by accumulation, and this part of the investment will definitely be converted into part of the price. Therefore, the most expensive operating expenses at present are promotion.

2: Design

In order to maintain the brand image, big-name glasses are generally very fine in terms of workmanship and decorative details. For the products of independent designer brands, the designer’s efforts and creativity not only beautify the decoration of the glasses, so as to create a “high-end” product. “Image, but also improved wearing comfort and convenience, these will also occupy a larger share of the price.

3: material

Good lenses have good optical performance, but poor lenses may have impurities, or they may not refract light well enough, which may cause damage to the eyes. : It’s just a piece of glass, why buy tens of thousands), and a good lens may also have anti-ultraviolet and anti-blue light functions, which will be thinner, and it will last a long time if you wear expensive ones. It can be used for about 3 years, and it is not suitable for Scratch, different frame materials, good toughness and lighter ones will be more expensive. Frames are roughly divided into metal, sheet and natural materials. (The most expensive of which is the natural tortoiseshell series) Titanium alloys are strong and light. The difference in material determines the texture, comfort and durability of glasses, and it is not easy for people outside the industry to cut corners.

4: craftsmanship

The craftsmanship not only determines the exquisiteness of the appearance of the glasses, but also the processing technology of the frame determines the precision of the glasses. A frame of poor quality, no matter how good the lens is, can not guarantee the accuracy of the parameters of the glasses, and the actual parameters of the lens may gradually change under the stress generated by the frame.

5: optometry and glasses processing technology

No matter how good the frames and lenses are, without accurate optometry parameters and precise processing technology, the glasses made are still unqualified. So far, in addition to the necessary instruments and equipment for the accuracy of optometry, an excellent optometrist is essential, not a computer capable of doing it. Excellent masters naturally have to match the corresponding income. If sales commission is the main income, no matter how good the technology is, it will not take too much time for optometry. Optical processing is the same.
