Who We Are?

SIOU began with the vision of its founder, Luciano Dourado, a forward-thinking innovator who recognized a critical need within the Brazilian optical industry. He saw that independent laboratories were being held back—not by lack of talent or ambition, but by the high cost and limited access to advanced digital lens technology. Determined to change the landscape, Luciano created SIOU with a simple but powerful mission: to empower labs with cutting-edge digital lens designs that were both exceptional in performance and accessible in price.

What began as a bold idea quickly became a movement. Through relentless innovation, a deep understanding of laboratory needs, and a commitment to fairness in pricing, SIOU grew rapidly. In less than a decade, the company rose to become the leading digital lens design provider in Brazil—trusted by independents nationwide who finally had the tools to compete confidently with major conglomerates.

Today, SIOU stands as a symbol of independence, innovation, and industry transformation, shaped by Luciano’s belief that world-class technology should uplift everyone—not just the biggest players. Now expanding globally, SIOU continues to deliver the same promise: premium digital lens designs that elevate quality, strengthen labs, and redefine what’s possible.
