• Supports focus, clarity, and cognition.

• Enhances sleep depth and recovery.

• Filters harsh light to protect vision.

Maximise your daily performance with Maxwell BlueSync – a precision-engineered lens system that enhances natural light exposure, protects against light stress, and keeps your body’s circadian rhythm in sync. Whether you’re on the move or working long hours, Maxwell helps you stay energised, sharp, and balanced from day to night.

BlueSync filters harsh light while boosting beneficial wavelengths, supporting optimal energy, mood, and cognitive function. By promoting circadian stimulation during the day, it also helps deepen and improve sleep at night. Ideal for frequent flyers, shift workers, or anyone facing irregular schedules, Maxwell helps keep your internal clock running smoothly.

Inspired by James Clerk Maxwell, the pioneering physicist who transformed our understanding of electromagnetism, this sporty rectangular frame combines form with function. Featuring a bold black finish, straight browline, sleek arms, and a clear saddle bridge, the look is refined yet assertive—designed for those who appreciate modern edge and subtle confidence. Fits medium to large faces.

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.
