My No. 1 sleep tip
I notice that I feel much more relaxed in the evening since I started using these glasses. I’ve also tried other brands, but with these I can really feel the difference.

Much better
I wear the glasses every evening while watching television and when I’m still on my phone. The red tint took some getting used to, but by now the glasses have truly become part of my evening routine.

Delightful
The glasses are surprisingly lightweight and comfortable. I can wear them for a few hours without any problems and notice that the harsh light from screens and lamps is much less intense.

I should have bought this sooner!
I regularly work on my laptop in the evenings and was looking for glasses that genuinely filter a lot of light. The difference compared with my previous clear blue-light glasses is enormous. Very satisfied with them.

From curious to convinced

Wear yellow lenses during the day (for example, while using a screen or under artificial light) to reduce fatigue and overstimulation. Red lenses are intended for the evening, when it is dark outside or approximately two hours before bedtime. They block all disruptive light frequencies that can disturb your biological clock and help you drift off to dreamland.



The yellow lenses filter 35% of the blue-light spectrum, particularly wavelengths between 380 and 455 nm. Light between 455 and 550 nm passes through, so you don’t unnecessarily block too much useful light during the day.



Yes. The metal flip-up mechanism has three positions, allowing you to easily switch between filtered and normal vision without having to remove the Clip-On from your glasses each time.

Absolutely. We’re bombarded with screens, light, and stimuli all day long. We often try to add something else on top (a pill, supplement, or trick). But sometimes removing the cause—in this case, blue light—is the real solution. Your eyes and brain can feel the difference.

The Clip-On is designed for most full-rim glasses. The fit may vary with rimless or half-rim frames. Thanks to its compact clip, you can easily attach it to your own glasses.

Many of our products are based on scientifically researched principles related to sleep, light, breathing, and recovery. Think of the effect of blue light on melatonin, or the benefits of nasal breathing for deep sleep.In practice, our customers often notice a difference after just the first night—physically and mentally. Some products require a short adjustment period, but the effects are quickly noticeable when you use them consistently.Want to track your progress accurately? Then we recommend using a sleep tracker or another measurement device. This way, you can also see the impact in numbers, alongside what your body and mind are already feeling.

No. The metal frame provides extra durability while remaining light and comfortable enough for extended use.

Use the included lens cloth to gently remove dust and fingerprints. After use, store the Clip-On in the protective case to prevent damage.

The Clip-On is ideal for working on a computer, gaming, studying, watching television, and scrolling on your phone or tablet. You can also wear it at the office or in spaces with lots of bright artificial light.
