Tempest Sunset – Mountain Forest uses sunset lenses that block 100% of melatonin-disrupting wavelengths, addressing the problem of evening light from screens and indoor lighting that suppresses melatonin and keeps cortisol higher than it should stay. By removing this interference, the lenses allow your body to follow its natural rhythm, produce melatonin at the right time, and shift into cellular repair mode. This supports deeper sleep with more REM cycles and helps your hormones rebalance overnight. The result comes from light control rather than stimulants or sleep aids, keeping the process aligned with normal biology.

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.
