Up to 99.9% of blue light and part of the green spectrum (380–550 nm). That’s exactly what you need to prevent light exposure from disrupting your melatonin production. And you can feel the difference: in your sense of calm, relaxation and sleep quality.

Our advice is to always request a test report from suppliers. Many glasses do not block the right wavelengths, making them ineffective. Test report available!

Yes, the image takes on a red tint. But you can still see what’s happening perfectly well. Many customers actually use the glasses while watching their evening series or a film. This way, you can still enjoy your favorite moments without compromising your sleep. You not only relax mentally, but also help your body wind down at the same time.

All day long, we’re bombarded with screens, light, and stimuli. We often try to add something else on top (a pill, supplement, or trick). Removing blue light may help support a greater sense of calm.

The updated version features a sturdy metal frame that feels more durable and premium. Nevertheless, the Clip-On remains light and comfortable enough to wear all evening.

The lenses don’t have a delicate, cheap coating like most blue-light glasses, but CR39 absorption lenses. They can easily be cleaned with the included lens cloth. Store and transport the glasses in the glasses case or the included box for extra protection.

We designed the clip-ons to fit any pair of glasses. If they don’t fit after all, you can return the product free of charge.

Many of our products are based on scientifically researched principles related to sleep, light, breathing, and recovery.

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.

Absolutely. The Clip-On is designed for everyday use during your evening routine. The lightweight metal frame combines comfort with a stylish look and is ideal for reading, watching television, and other screen use.
