Key Benefits

TrueDark Sunsets™ Fairlane are designed for the early evening, when light exposure still matters but full red lenses are not yet needed. The red-to-yellow gradient lenses block 99 percent of blue and violet light and up to 93 percent of green light, helping protect melatonin while allowing enough visual clarity for work, screens, and social time.

The classic square frame is crafted from lightweight, durable polycarbonate and finished in matte black for a clean, everyday look. Polarised lenses reduce glare and block 99 percent of UVA and UVB rays without distorting natural colour perception. Ideal for screen-heavy lifestyles, Sunsets™ Fairlane support a smoother transition into night, reducing eye strain while helping maintain a healthy circadian rhythm.

Each pair includes a foldable hardshell case and a microfibre lens cleaning cloth.

Light doesn’t just help you see. It tells your brain how to feel and when to switch on or off. TrueDark focuses on managing what the brand calls “junk light” — artificial blue, green, and violet wavelengths from screens and modern lighting that interfere with your circadian rhythm. Unlike basic blue-light glasses, TrueDark lenses are designed to filter specific wavelengths at different times of day, helping reduce overstimulation and support more natural sleep and focus patterns. 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. It’s a practical tool for navigating modern light exposure, not a fashion accessory.

TrueDark was founded by Dave Asprey after years of struggling with poor sleep caused by artificial lighting. When standard blue 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. Designed as a sleep, focus, and performance tool, TrueDark exists to help people feel better by fixing light at the source.
