Nooner™ — daytime blålysbriller for the hours your eyes take the most damage
Blue light isn't the enemy in the morning — your body needs it to anchor your sirkadisk rytme and stay alert. But from 11am onwards, it stops helping and starts hurting. Nooner glasses are designed for that window — the circadian dead zone where blue light no longer does anything useful for your biology but keeps building eye strain, oxidative stress, and afternoon fatigue throughout the working day.
💡 The circadian dead zone — why timing matters
Your body responds differently to blue light depending on the time of day. In the morning, blue light is essential — it raises cortisol, suppresses melatonin, signals wakefulness, and sets your internal clock. Blocking it then would be counterproductive. After around 11am, that circadian signal has already been sent. Blue light no longer contributes to your alertness or clock-setting. What it does continue doing is generating oxidative stress in your retina, contributing to digital eye strain, and accumulating the kind of fatigue that hits hard by 3pm.
Nooner glasses provide balanced protection in that window — reducing strain without disrupting daytime alertness. Think of them as sunglasses for indoor kunstig lys. For a deeper look at what blue light actually does to your biology at different times, Dominic's guide to indoor lighting in Norway covers the full picture.
🇳🇴 Why this matters especially in Norway
🌑 Norwegian winter work hours
From November through February, many Norwegians never see natural dagslys during work hours. You arrive at the kontor in darkness and leave in darkness. Every photon of light you receive comes from artificial sources — LEDs, monitors, overhead lighting — all emitting concentrated blue wavelengths that weren't designed to be your only light source for 8+ hours.
💻 Indoor screen culture
Norwegian kontorkultur means long hours at computers, often with limited access to windows. Multiple screens, fluorescent overhead lighting, and long indoor sessions create a perfect storm for digital eye strain. Nooner glasses reduce the cumulative load without affecting how you do your job.
⚖️ The balance you need during the day
You still need some blue light during the day to stay alert — that's why Nooner glasses don't block it completely. They filter just enough to reduce strain and oxidative stress while still letting your brain recognise it's daytime. For the evening, you switch to AfterDark glasses for full melatonin protection.
Two lens options — both designed for daytime use
💎 Clear lens — all-day protection
- All-day use from 11am onwards
- Essentially normal colour perception
- Suitable for design work, video calls, and colour-critical tasks
- Office and professional environments
- For those who want gentle protection without any tint
🟡 Yellow lens — afternoon protection
- Afternoon use — after lunch through early evening
- Significant eye strain reduction for heavy screen sessions
- For harsh fluorescent or LED kontorbelysning
- Gaming during daytime hours
- For those with high sensitivity to blue light or frequent skjermhodepine
Both are for daytime use only. Switch to AfterDark glasses from early evening for melatonin protection.
⏰ Your circadian-friendly daily schedule
☀️ Morning — before 11am
No blue light blocking. Your body needs morning blue light to anchor your sirkadisk rytme, raise cortisol, and set your internal clock. Seek out natural dagslys where possible, or use a light therapy lamp if you're in a dark Norwegian kontor.
💻 Midday to afternoon — 11am to 6pm
Nooner glasses recommended. The circadian dead zone. Blue light no longer helps your body clock but continues causing eye strain and oxidative stress. Clear lenses for all-day work; yellow lenses from afternoon onwards if you have heavy screen load.
🌅 Early evening — 6pm onwards
Switch to AfterDark Sundown (orange). 98.5% blue light block for winding down while still being able to see well. AfterDark glasses here.
🌙 Pre-bedtime — final hour before sleep
Switch to AfterDark Moonlight (red). 99%+ block of all sleep-disrupting wavelengths — maximum melatonin protection. AfterDark glasses here.
💡 Do not wear Nooner glasses in the morning. Your body needs that early blue light. Start wearing them from 11am onwards.
⚙️ Frame and lens quality
- TR90 memory polymer frame: Lightweight, flexible, and hypoallergenic — comfortable for all-day wear without pressure on the nose or temples
- CR39 optical lenses: Standard for quality optics — better clarity than polycarbonate, scratch-resistant coating for daily use
- Spectrometer-tested: Each lens is tested for precise filtering performance — not a claimed percentage
- Anti-reflective properties: Reduces screen glare — reduces the squinting and muscle tension that contributes to kontorhodepine
- Professional appearance: Suitable for any workplace — does not look like safety goggles or gamer glasses
- CE certified: Meets European quality and safety standards
- 12-month warranty: Quality guarantee from Dominic directly

From Dominic
I wear Nooners from midday at my desk. Not because I think they're transformative on their own — they're not — but because when you're spending 8 hours under Norwegian kontor lighting in the middle of vinter, the cumulative load of artificial blue light on your eyes and your mitochondria is real and measurable. The clear lenses are essentially invisible to anyone who doesn't know what they are. I've had customers tell me the afternoon headaches they'd accepted as normal just stopped within a few days of consistent use. That's not a dramatic claim. It's just removing a constant low-level stressor.

❓ Vanlige spørsmål / Common questions
What is the difference between clear and yellow lenses?
Clear (40% block) is for all-day computer use from 11am — colour perception is normal, suited to design work, video calls, and office environments. Yellow (75% block) is for afternoons and heavy screen sessions — more protection, visible warm tint, better for extended reading or harsh kontorbelysning. Not suited to colour-critical work.
Hvorfor skal jeg ikke bruke blålysblokkere om morgenen?
Your body needs blue light in the morning to anchor your sirkadisk rytme, boost cortisol, and set your internal clock for the day. Blocking it then would delay wakefulness and shift your circadian phase. Nooner glasses are for 11am onwards — the circadian dead zone where blue light no longer helps but continues straining your eyes.
Are Nooner glasses a replacement for AfterDark evening glasses?
No — they serve completely different purposes. Nooner (40–75% block) is for daytime eye strain reduction — not melatonin protection. AfterDark (98–99% block) is for evening use to protect melatonin. Using Nooner in the evening instead of AfterDark would not adequately protect your søvn.
Passer disse til kontorbruk i Norge om vinteren?
Yes — designed for exactly that context. In Norwegian vinter, many workers never see natural dagslys during work hours. All light exposure comes from artificial sources for 8+ hours. Nooner glasses reduce the eye strain that builds up through those sessions without disrupting your daytime alertness or making you look strange at the kontor.
Can I wear these glasses all day?
Clear lenses (40% block) are suitable for all-day wear from 11am. Yellow lenses (75% block) are better suited to afternoons only. Switch to AfterDark orange or red lenses from early evening regardless of which Nooner lens you use during the day.
Er det nødvendig med dagbriller i tillegg til kveldsbriller?
They serve different purposes. Evening glasses (AfterDark) protect melatonin — that's their primary function. Daytime glasses (Nooner) reduce eye strain and oxidative stress during work hours. If you only use one type, evening use has the greater impact on søvnkvalitet. Daytime use reduces accumulated digital fatigue.
What lens material are the Nooner glasses?
CR39 optical lenses — scratch-resistant, anti-reflective, and spectrometer-tested for precise filtering. The frame is TR90 memory polymer — lightweight, flexible, and hypoallergenic for all-day wear comfort.

Protect your eyes through the working day
Nooner glasses sit in the gap between morning alertness and evening melatonin protection — reducing the strain that accumulates silently through hours of Norwegian kontor work. Start from 11am. Switch to AfterDark in the evening. Done.
Usage note: Do not wear Nooner glasses before 11am — your body needs morning blue light. Yellow lenses are for afternoon use only; switch to clear for all-day wear. Always use dedicated evening glasses (AfterDark) for melatonin protection — Nooner glasses are not designed for that purpose.
