Are Raytheon lenses imported?

Yes Ruileshi series optical lenses adopt the patented optical technology of Yosemite in the United States, and the original 28-layer coating process improves the transparency, hardness and toughness of the lenses, thus improving the comfort of the wearer. They are imported from America. Lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After polishing, they are often assembled with spectacle frames to correct users' vision and obtain clear vision.
