Wind down with Nate Sunset – a sophisticated frame named in honour of Nathaniel Kleitman, the father of modern sleep research. With its square tortoise shell design, soft curves, and clear saddle bridge, this style offers a refined wrap-around feel for comfort and confidence as the day winds down.

Each pair features Ra Optics lenses, scientifically proven to block 95–100% of artificial blue light, essential during evening hours when screens and indoor lighting can disrupt your sleep cycle. Nate Sunset helps ease visual fatigue and overstimulation, supporting better brain function, improved energy, and deeper, more restorative sleep.

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.
