Spectacle lens selection

Many people are asking about how to choose the brand of eyeglasses. In fact, I think that we should not be too entangled to choose which brand, the four major international brands can meet the more demanding needs of consumers, but each brand has its own patented products and conventional products. Unless you have to choose some special patented products (such as Zeiss driver mirror, Essilor S series, etc.) must choose their brand, all international famous products can meet the most basic clear, clean, ultra-thin, wear-resistant requirements of customers.
So what do you need to choose as a regular consumer (single-lens lenses, not including progressive series)?

1, wear lasting supreme: Essilor drilling crystal A3 series of film, BBGR series, Zeiss diamond cubic platinum film are currently the most durable lenses on the market, hard film has been confirmed by the market.
2, imaging-based: camera lens company's lenses, such as Zeiss, Nikon, PANTAX, etc., camera lens design is higher than the conventional spectacle lens design, its brand of high-end lens series can maintain all angles of vision.
3, ultra-thin-based: In addition to the market selection of 1.67, 1.71, 1.74 according to the refractive index, it should also be noted that the double-sided aspherical lens is thinner than a single surface, the larger the refractive index of the same refractive index, the thinner the lens, such as the Japanese famous The diameter of the lens and Essilor 1.67 can reach 80mm, and the smaller the diameter of the same refractive index mirror is, the thinner the height can be considered.
4, technology-based: companies continue to launch their patented products, not other companies will not, can not do, such as Essilor anti-fog, Zeiss driver driving mirror, Kemi SEENET.
5, to meet the general needs, cost-effective: national brand Mingyue lenses and internationally renowned brands of low-end lenses are more cost-effective competitiveness, South Korea Kemi for France Essilor high-end single-lens lenses more cost-effective.

Overview, buy the main series of lenses from domestic and foreign famous manufacturers, because these are the company's largest lens in order to invest in the market, do not listen to the words of the store, after all, business is not good; do not buy for the company's reputation The lens with the lowest price, don't think that the quality of a brand is the same. After all, international famous products have low-priced products that only compete for the local market. After spending a lot of money, they can't reach the imagination level.
