Teton Gravity Research (TGR) recently dropped its TGR Sun Optics collection of sunglasses handmade in Italy with polarized lenses by Carl Zeiss.

Under development by TGR designers and partners at Zeiss since 2018, the collection is the next step in the evolution of TGR Optics.

TGR has traveled the world for the past 25 years in the harshest conditions using Zeiss camera lenses for its cinematography. Now it incorporates the same technology and research into its sunglass collection featuring polarized lenses. And in line with TGR’s commitment to reduce its carbon footprint, the frames are made in a 100 percent solar-powered factory less than five miles from the Zeiss’ lens manufacturing plant.

“We live our lives behind the lens, so we wanted to set the standard with TGR Optics. Carl Zeiss knows how important vision and optics are to what we do, so it was an easy decision to work with Zeiss on our polarized lens technology. The Italians know lenses and sunglasses better than anyone, so we were incredibly stoked to partner with one of the most reputable and sustainable factories in the world,” said TGR Co-founder Steve Jones.
