Recommended series: A4 diamond series
 
As an optical group formed in 1972 by the merger of two French optical companies, Essel and Silor, Essilor has a history of nearly 160 years and is on par with ZEISS. Essilor Group is a veritable M&A freak, with eyewear brands such as Tyrannosaurus, Mosen and Wanxin, which are well known to mainland consumers, all bought shares. As the group's own optical lens brand, Essilor is different from Zeiss and TAG Heuer, which can only appear in collection stores, it has independent stores and is equipped with optometry equipment that is at the forefront of the industry, and offline experience is recommended.
 
Since Rodtenstar and Nikon's lenses are relatively niche in the Chinese market, the main competitors for Essilor lenses fall to Zeiss and TAG Heuer. As a best-selling mass lens, Essilor has always led the sales lead, but it is still a long way from the two in terms of customization technology and coating design.
 
Just like the diamond cube film for ZEISS, Essilor also has its own most representative diamond crystal coating layer, which is equipped with the main diamond crystal series products, which has basic functions such as anti-reflective, anti-fouling and waterproofing, and the main difference is in the protection against ultraviolet and blue light. Among them, the A series is the outer surface UV protection, the A3 series is double-sided UV protection, and the A4 series is double-sided UV protection and blue light. In fact, in the feedback of most wearers, the difference between A3 and A4 is not much, and it is inferior to the UV protection effect of Zeiss lens substrate, and the quality is relatively mediocre.
 
Essilor's advantage lies in the wide range of product price gradients, which can meet the needs of different consumer groups. The price of ordinary spherical lenses is less than 500 yuan, and the A3 or A4 aspherical lens with a refractive index of 1.60 can be won within 2000 yuan.
 
With the trend of various brands using resin as raw materials, Essilor is one of the few brands to offer PC lenses. It launched a series of cosmic lenses, which are ten times more impact-resistant than ordinary plastic lenses, lighter and more wear-resistant, suitable for outdoor sports. The series is also available in A, A3 and A4 depending on the coating layer, the price is between 880-1380, and only 1.59 refractive index is available, which is suitable for people with low to medium power within 800.
 
As the pioneer of progressive lenses, Essilor's Wanlilu series is more used in vision correction for middle-aged and elderly people, with high prices and average sales in the domestic market. If you are buying a conventional single vision lens, Essilor is not much different from Nikon, which has a close cooperation with you, and if you need a customized progressive lens, we recommend Nikon, which is superior in imaging technology.
 
Compared with the ZEISS Color Vision series, which only has gray color change, Essilor's color changing tablets are available in tea, gray, and green, and its diamond crystal full line of sight color changing tablets have been launched to the seventh generation, covering a conventional refractive index of 1.50~1.67, and a variety of drill crystal film layers from A to A4. The Transitions series has mature color-changing technology, and the lenses are sensitive to sunlight and can effectively block ultraviolet rays and glare, but compared with Zeiss chromic lenses, they are slightly inferior in light transmittance, and the price of a pair from 2000 is also a bit expensive.
 
It is worth noting that there is a lot of confusion in the mainland lens market, with Essilor, which has a high sales volume, bearing the brunt of counterfeit products in the market. When purchasing, consumers should pay attention to distinguish whether the merchant has a formal authorization letter for the brand, so as to avoid buying counterfeit and shoddy products and harming their own interests.
