The perfect complement to TrueBlockers
Your eyes deserve darkness. Your brain demands it.
The 3D Trueblock Sleepmask is the ideal partner to your TrueBlockers — combining 100% light protection at night with 100% blue light blocking during the day.
Together, they form a complete circadian system that protects your sleep, focus, and hormonal balance.
And yes — it’s not just a feeling.
Peer-reviewed studies confirm that sleeping in total darkness improves melatonin production, increases REM quality, and enhances recovery overnight.
Total darkness. Total recovery.
You can’t control life’s chaos — but you can control how deeply you rest.
The 3D Trueblock Sleepmask by Jon Blund™ is designed to give you complete darkness, total comfort, and the kind of sleep that resets your mind and body.
Forget thin, hot, and leaky masks. This is next-generation sleep tech, engineered to block 100% of light while staying soft, breathable, and weightless on your face.
