TrueDark

Block all junk light and experience better sleep with TrueDark glasses.

TrueDark was founded by Dave Asprey after years of struggling with poor sleep caused by artificial lighting. When standard blue light blockers failed to make a meaningful difference, he worked with neuroscientists and circadian biology experts to develop a more complete light-management system. The insight was simple: blue light isn’t the only problem; green and violet light also affect brain signalling when exposure happens at the wrong time.

TrueDark lenses were created to block the right wavelengths at the right moments, helping people better align with their natural 24-hour rhythm. Plus, TrueDark is the only brand backed by EEG-verified research showing brainwaves can shift from alert beta states into calmer alpha and even deep-sleep delta states.

Designed as a sleep, focus and performance tool, TrueDark exists to help people feel better by fixing light at the source. As a UK stockist of TrueDark glasses, browse the selection at Healf.
