At Serengeti we’re not just concerned with what’s in front  of the eye, we are intensely focused on the eye itself. Helping people see more clearly is what drives all our innovation. By doing this, we’ve revolutionized the way the world looks at, and through, sunglasses. We are driven by vision, and have been since the beginning. Our evolution over the past century follows an unparalleled path of achievements in technology, design, and performance.
