Yellow lenses are worn during the day (for example, behind your screen or under artificial light) to reduce fatigue and overstimulation. Red lenses are for the evening, when it is dark outside or about two hours before bedtime. They block all disturbing light frequencies that can disrupt your biological clock and prevent you from drifting off to dreamland.

Up to 99.97% of blue light and part of the green spectrum. That is exactly what you need to prevent light from disrupting your melatonin production. And you will notice the difference: in rest, relaxation, and sleep quality. Test report available!

Yes, the image takes on a red glow. But you can still see what's happening perfectly well. Many customers use the glasses during their evening TV series or movie. This allows you to enjoy your favorite moment without it affecting your sleep. Not only do you relax mentally, but you also help your body to switch off at the same time.

Absolutely. We are bombarded with screens, light, and stimuli all day long. We often try to add something extra (a pill, supplement, trick). But sometimes removing the cause, in this case blue light, is the real solution. Your eyes and your brain will feel the difference.

Yes, most customers quickly find a suitable size. Check out our size chart for the right fit. And good to know: women say that the glasses also fit well in their hair—no weird bumps or kinks.

Many of our products are based on scientifically researched principles relating to sleep, light, breathing, and recovery. Consider 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 one night—both physically and mentally. Some products require a short period of adjustment, but the effect is quickly felt when used consistently. Would you like to accurately track your progress? We recommend using a sleep tracker or other measuring device. This allows you to see the impact in numbers, in addition to what your body and mind already feel.

Ja, je draait de lamp op dezelfde manier in de fitting als een gewone lichtbron. Controleer voor het plaatsen altijd of de lamp is uitgeschakeld en of de fitting geschikt is voor E27.
