Cardino lens is a subsidiary of Vision Unlimited, which has a super-strong water film layer and excellent light transmittance. I use Catinaud, which I find particularly clean. It's still so clean after a year of use. The most important thing is that it is particularly bright and comfortable to wear, mainly to prevent blue light.

Oushijia lenses produced by Danyang, Vision Unlimited Glasses Company, is a lens sales company jointly established by several large lens wholesalers, and the lenses are OEM lenses. The quality is ok. Compared with Zeiss Komi, there is still a gap.
