Story

In 2011, our journey began with a heartfelt mission. Our founder, a researcher at UPenn, designed a pair of colorblind glasses for his best friend, who had long struggled with color deficiency. Witnessing the joy and wonder of seeing color for the first time was a life-changing moment—one that sparked the creation of Pilestone.

What started as a simple act of friendship has now grown into a global movement. With branches around the world, we've helped over 40,000 people experience the beauty of color. At Pilestone, we believe everyone deserves to see the world in its full vibrancy, and we’re honored to be part of that journey.
