Go to Seiko optical shop. It's a time-honored brand. Now it's opened in Baiteng Digital City, the overpass of Science and Technology Commission, and its head office is in 404. I compared it at their house. The quality can't be said, and the price is right. I don't think it's good for Bao Dao and Wan Shun. Everything recommended is expensive, and the products used for activities are not good. It's just that they have a lot of publicity
