District Vision Keiichi Calm-tech Sunglasses

District Vision focuses on teaching people meditation to maximize their workouts, train smarter and exercise in a way that is best for an individual’s body. The brand also offers high-performance sunglasses to support those pursuits. “Humans need little rewards along the way,” says Max Vallot, cofounder of District Vision. “If you go and torture yourself through a marathon, it goes a long way to get your special running shoes for the marathon, or your special eyewear, or whatever it is.”

This year, the brand updated its perennial-favorite Keiichi frame with the world’s first porous, anti-fog lenses, Calm-tech. “Lens condensation is the major issue in sport optics mainly because it’s impossible to control the temperature of your face, the environment and the lens,” says brand cofounder Tom Daly. The Calm-tech material, originally developed for car screens in Japan but never available to the public, is a membrane that absorbs moisture to remain clear.

“We develop custom-lens programs by playing with three variables to reduce eye strain: light transmission, tints and protection [against UVA/B/IR],” Daly says. “It’s essentially an experiment for us at District Vision to mix these in different ways with the hypothesis that relaxed eyes and facial muscles improve the eye health and mental clarity of the runner.”

The Calm-tech lenses were designed for athletes who wear sunglasses for hours at a time or in challenging performance situations, like marathon runners, cyclists, climbers and skiers. These athletes can’t repeatedly break to wipe foggy lenses and shouldn’t have to strain to see clearly. In the past, eyewear companies tried to create anti-fog lenses with chemical coatings or special venting, but now, the magic’s in the material.
