The world’s finest cameras, microscopes, telescopes, binoculars, and sunglasses all have one thing in common: ZEISS Certified lenses.

ZEISS Certified lenses are made in Italy by the legendary experts at Carl Zeiss Vision Sunlens, the company that pioneered high-performance optics back in 1846. Every ZEISS Certified lens is formed in a proprietary diamond-polished mold for flawless clarity, and subjected to a rigorous 24-step quality procedure that ensures the highest quality and performance possible. To guarantee the performance of ZEISS Certified lenses, each lens is inspected throughout the manufacturing process, and laser etched with a “Z” icon after final inspection. A certificate of authenticity ships with every ZEISS lens, and promises the clearest, most accurate vision possible without distortion, while meeting the toughest standards in the industry.
