How does the LenBlu® lens filter blue light?
The LenBlu® lens has a blue light filter coating. This layer reflects part of the high-energy blue-violet light, the one with the shortest wavelength, given off by screens, phones and LED lights, before it reaches your eyes. That’s why, at some angles, you’ll see a soft bluish reflection on the surface: that’s the filter at work. Unlike yellow or orange lenses, ours is clear, with just a hint of warmth, and it doesn’t change the colors on your screen. Non-prescription, with a light and flexible TR90 frame.
Do they really work? Are they worth it?
Yes, if you know what they do. You’ll hear every opinion about blue light glasses, but researchers have been studying for years how artificial blue light affects our day-night rhythm (the circadian rhythm): at night, screens and LEDs keep the brain in “day mode”. LenBlu® glasses filter part of that light with a clear lens, so you can enjoy your hours on the computer, your phone or your series more comfortably, at night too.

What does the blue light filter do?
Computer, phone and TV screens, and much LED lighting, emit blue light. LenBlu® lenses have a built-in filter that reduces part of that light before it reaches your eyes, in a clear lens that keeps colors true. If eye discomfort doesn't go away, see an eye care professional.
Are they prescription glasses?
No. The lenses are non-prescription, with no correction. They suit you if you see well without glasses or wear contact lenses.
What size are they? Will they fit?
One size, designed to fit most adult faces. Measurements: lens 53 × 45 mm (2.1 × 1.8 in), bridge 18 mm (0.7 in), total width 142 mm (5.6 in) and arms 138 mm (5.4 in).
To check, look at the numbers printed on the arm of your current glasses (for example, 53□18-138). If they're close, the fit will be similar. The frame is flexible and adapts comfortably to your face.
Do the lenses change how colors look?
Colors stay true. The lens is clear, so your screen, photos and shows keep their natural colors.
At certain angles of light you'll see a very soft blue reflection on the lens surface: that's the filter coating.
Can I wear them all day?
Yes. They're light and flexible, made for all-day wear. Wear them at your computer, on your phone, watching shows, and out and about too.
What's in the Duo Pack?
Both pairs of LenBlu® glasses, Clear and Matte Black, each with a blue light filter and non-prescription lenses.
It costs €49.99. To switch styles with the day, or to share them with someone.
How long does shipping take, and what does it cost?
Shipping to Spain takes 5–8 business days. Once it ships, you'll get an email with a tracking number.
