Key Benefits

  • Blocks 99% of blue and violet light.
  • Filters up to 93% of green light.
  • Supports melatonin while maintaining evening alertness.
  • Reduces eye strain from screens and lighting.
  • Lightweight polycarbonate frame for everyday comfort.


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.

Why TrueDark is Healf
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.

The best wellbeing website…

The best health and wellbeing website in the UK. The range of products is fantastic, even on hard to reach USA products. I love the subscription service too. I'd be lost without this website.

Alex

Amazing!

Healf isn't just another wellbeing brand. They really get it. The products are fantastic, and the support is always so personal and genuine!

Janet

Great products, service, and customer support

Healf have a great range of wellbeing products not available elsewhere in the UK. They are competitively priced as one-off, but even better if you take up the 'subscription' which is super flexible too. I'd have no hesitation in recommending Healf.

I love Healf

It's the only place I get really decent health and wellbeing brands, particularly US brands. I've bought a Pvolve set, lots of Skinny Confidential stuff, Thorne supplements etc., the really great stuff that's impossible to get otherwise.
