Whether glasses are expensive or not is not a subjective decision. It must be decided according to actual needs and circumstances.
For example, if the high myopia exceeds 1000 degrees, it is obviously unrealistic to have a 1.56 thick lens. But if it is equipped with a 1.67 or 1.74 ultra-thin lens, the price will definitely rise, because the material, process, cost, etc. will be much worse.
For example, people engaged in special occupations, such as electric welders, must inspect glass lenses. They cannot be matched with resin lenses, and the price is not as cheap as ordinary resin lenses.
Third, many users bought glasses at the optical shop at their doorstep, and they felt it was cheap. Later, they went to a business district in a big city to buy a pair of glasses, which felt similar to the original glasses, but the price doubled. So the spectacle shops in big cities are cheating people. In fact, the rent and wages in big cities are not calculated, which cannot be compared with shops in small cities and non-commercial circles. It is also an objective factor in the price difference.
In addition, the purchase price of glasses cannot be simply seen, but the function, film layer, etc. of the lens should be distinguished. After all, the optical performance and additional functions of most lenses are achieved through the film, and the electroplating process determines the quality of the product. Why are many lenses of Zeiss and Asiluo so expensive?
A single "branded product" cannot be explained clearly. The R&D capabilities and manufacturing technology behind these brands are excellent in the world. The cost is naturally very high. Therefore, the price is slightly higher and there is no thickness. As a result, the price of R&D personnel is high, and the advanced equipment is also high. The hyperbolic cosine value of. The hyperbolic cosine value of.
Therefore, it is necessary to have expensive glasses, just like you have to buy expensive medicine for a certain disease. Most people cannot make a subjective decision. Depends on actual needs.
