With square frames in a rich tortoise shell hue, subtle curves, and a clear saddle bridge, this medium-fit design is ideal for those who prefer a frame that wraps with comfort and style.
Ra Optics lenses are scientifically proven to block 95–100% of artificial blue light, helping to protect your health from constant exposure to screens and indoor lighting. Wearing Nate Daylight can help reduce eyestrain, headaches, and fatigue while supporting energy, mental clarity, and quality 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.
