1. Higher price: Wanjinbao glasses belong to high-end glasses brands, and the price is relatively high.
2. Lens grinding problem: Wanjinbao's rimless diamond-encrusted glasses may have some problems during grinding. Because the rimless edge is polished into a mirror surface, which happens to be a lens with a certain curvature, the light refracted into the lens after hitting the edge of the lens may cause serious glare.
