Ra Optics was founded by Matt Maruca after his own health journey led him to uncover the effects of artificial light on circadian biology. His mission became clear: to create the world’s highest-quality blue-light-blocking eyewear, backed by peer-reviewed science and guided by ancestral principles. Crafted with proprietary lens technology, Ra Optics glasses are engineered to protect mitochondrial function, regulate melatonin production, and reduce the impact of screen-induced fatigue. It’s a deceptively simple tool, designed to restore one of the body’s most critical rhythms—light and darkness.
