Wanxin is the first "China Famous Trademark" in China's eyewear production industry, formerly known as Situ Lens Factory, founded in 1973, and is the longest-running lens brand in China, which is in the same gradient as Mingyue. Due to the great technological progress of Mingyue in recent years, Wanxin has become a regular force, and has become a supplementary force for the group's low-priced lenses after being purchased by Essilor.
 
The composite coating of Wanxin lenses is Leybold film, which has basic properties such as anti-reflective, dustproof and wear-resistant, and has high hardness, which is used in anti-blue light series lenses to meet the needs of daily protection. Compared with Mingyue lenses, Wanxin's conventional refractive index is only about 1.60, so the price is lower, and a pair of basic lenses can be configured within 300 yuan.
 
If you want to try self-tinting lenses, Wanxin has two options: base change and film change, and the prices are 188 yuan and 388 yuan respectively. The photochromic lenses with film change are faster and the overall performance is better than that of base color change. Of course, Wanxin's photochromic lenses are far inferior to big brands such as Essilor in terms of substrate and process, and can be seen at an affordable price as an entry choice for photochromic lenses.
