Tempest Daylight - Mountain Forest

Tempest Daylight - Mountain Forest uses daylight lenses that selectively filter harmful blue light while preserving beneficial wavelengths, addressing the strain caused by modern LED and screen exposure. This approach helps reduce digital eye strain, headaches, and fatigue without blocking light your body still needs during the day. By supporting healthier light input, the lenses help stabilise stress hormones and protect cells from ongoing light-related stress. The result feels more balanced and natural than simply dimming or darkening your view. Energy levels and mental performance stay steadier across long screen sessions.

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.
