Begin your journey to better sleep, more energized days, sharper focus and improved mood with TUO Circadian Smart Lighting.

TUO is partnered with the University of Washington, one of the world's top research centers for vision and neuroscience. Scientists there have recently discovered amacrine cells in the eye. These highly light-sensitive cells are the cells that TUO's patented, industry-leading technology affects to influence your circadian rhythm. TUO is more effective than anything else on the market and is the only circadian light therapy product that works at normal brightness levels and reasonable distance.
