Uncompromising Product Quality Standards

JINS always strives for "Zero Compromise" to improve product quality. This is to enrich our customers' lives through our products.

JINS's product quality standards conform not only to ISO standards (ISO 12870 and others) used by eyewear manufacturers around the world, and to the former JIS (Japanese Industrial Standards) in Japan, but also to our own internal standards and up to 14 inspections and visual inspections by humans in the final stage. We also use Europe's EN Standard that is widely used around the world for calculating blue-light blocking percentage. We take pride in making world-class products that meet strict international standards.
