Zack Moscot, an eyewear designer for the company founded by his great-great grandfather, says he looks to old models for inspiration. "We choose to replicate them the way that they were done because they're such good quality," he says. Subtle changes in recent offerings such as the Sun Collection include experiments with the thickness of different frames, new colors, and lens gradients. Still, when Zack wants to be cutting edge, he looks at the archives and ponders what can be created with traditional crown glass and acetate production.
