Each pair features Ra Optics’ advanced lens technology, scientifically proven to block 95–100% of artificial blue light. This helps reduce digital eyestrain, screen-related headaches, and mental fatigue, while supporting steady energy, sharper focus, and deeper, more restful sleep.
Yogananda Daylight brings together iconic style and light-based wellness to help you feel aligned, energised, and mentally clear from sunrise to sunset.
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.
