Both countries are good at reading glasses.

The raw materials of glasses lenses are better in Japan, which has the largest market share, and are characterized by strong wear resistance and reflectivity.

German glasses have the characteristics of precise grinding, exquisite optical curved surface design, excellent light transmittance and anti-reflection performance, and excellent visual imaging quality. Sit firmly in the first place in the field of optical lenses. The lens series includes A series, cutting-edge, cutting-edge and sharp.
