What is XBLUE?

XBLUE is the name of Nordew's blue-light eyewear range. Everything we make has one goal: take the cold blue light out of your evenings so your eyes can rest and your body can start winding down on time.

Our goal

We live in front of screens (work, phone, TV) right up until bedtime. The problem isn't the screens themselves, it's the blue light they put out late in the evening. XBLUE exists to make protecting both your eyes and your sleep effortless, without having to switch the screen off.

What is "anti blue light"?

Visible light is made of different wavelengths. The blue part (around 450–480 nm) carries the most energy and has the biggest effect on your body clock. During the day that's good, it keeps you alert. In the evening it tricks the brain into thinking it's still daytime and slows the sleep hormone melatonin.

Blue-light glasses use tinted lenses that filter out exactly those wavelengths before they reach your eye. The result: less eye strain at the screen and a body that's allowed to start preparing for sleep on time.

In short: amber and wine-red lenses block the high-energy blue light. The warmer the tint, the more they block, and the closer to bedtime they belong.

Why these glasses?

We didn't want one pair meant to suit everyone. Different faces, different styles, different times of the evening. So XBLUE is several models sharing the same quality lenses:

  • Kitty: cat-eye, for a little attitude.
  • Halo: soft round-square, a timeless pick.
  • Nocturne: clean rectangular frame, understated and classic.
  • Stockholm: our signature model with both amber and wine-red lenses.

All with the same focus: removing most of the blue light in the 450–480 nm range, with an anti-glare coating that cuts reflections.
