Key Benefits

• Helps reduce eye strain from artificial light sources.

Enjoy visual comfort from sunset to bedtime. Sunset Lenses are engineered to filter out 100% of artificial blue and green light, helping to shield your eyes from the effects of screens and indoor lighting.

Inspired by the pioneering work of biophysicist Fritz-Albert Popp, the Crystal Frame combines contemporary design with a nod to scientific heritage. With its sleek rectangular shape and distinctive tinted lenses, this frame is crafted for those who appreciate both quality and standout style.

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.
