Power through your day with Clyde BlueSync – eyewear engineered to support your circadian rhythm and sharpen both mental and physical performance. By enhancing beneficial light and filtering the most harmful wavelengths, BlueSync helps you stay energised, focused, and in sync with your natural rhythm.

Each pair actively stimulates your circadian system, helping to increase daytime alertness, improve mood, and optimise cognitive function. The benefits don’t stop at sunset—this light balance continues to support deeper, more restful sleep at night. Whether you’re working shifts, adjusting to jet lag, or recovering from late nights, BlueSync keeps your internal clock on track.

With a clear, contemporary frame inspired by medical geneticist Clyde Edgar Keeler, the design pairs modern curves with a transparent saddle bridge for a comfortable and stylish fit. Suitable for medium to large faces, it offers enhanced clarity, reduced glare, and all-day comfort.

BlueSync uses advanced photobiology to deliver targeted light therapy through its lenses. Designed in collaboration with a leading expert, it filters harmful UVA, UVB, and high-energy visible light to protect cells from damage, while allowing regenerative red and near-infrared light to pass through. It emphasises long-wavelength blue light—peaking at 480nm—which plays a key role in activating the circadian rhythm, the internal clock that drives energy, mood, focus, and physical performance. This selective transmission supports both biological protection and daytime stimulation in perfect balance. With BlueSync, you can gain improved focus, enhanced energy, and better sleep—all from a single pair of lenses.

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.
