Satisfaction increased to 300! What kind of lenses are good for Essilor Wanxinbao Shijie spectacle lenses? What I am carrying now is a non-ball ball~

1. Essilor is a French brand, and its marketing is very successful. It is currently the number one brand in the country, and the quality cannot be said; Wanxin is among the top three domestic brands, and Bao Shijie is a first-line brand in Wanxin, and the quality is also very good. You can choose which brand according to your financial ability.

2. 1.56 means refractive index, which is a parameter that measures the thickness of the lens. The larger the number, the thinner the lens. Depending on your luminosity, choosing a refractive index of 1.56 is sufficient.

3. The prices of these two brands are uniform across the country, but each store may have different discounts depending on its marketing plan.

4. Essilor’s anti-counterfeiting mark is in the form of “Essilor”, which can be seen on the outer surface of the lens; Baoshijie is not in business, so I don’t know much about its anti-counterfeiting. It seems to be a circle. There is "-A" in the circle.
