Nooner - Daytime Blue Light Glasses for the Hours Your Eyes Take the Most Damage
Blue light is not 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 the kind of afternoon fatigue that makes the last two hours of the working day feel harder than they should. For a deeper look at what blue light actually does at different times of day, Dominic covers it in the guide to indoor lighting and light management in Norway.
The circadian dead zone - why timing is the whole point
Your body responds differently to blue light depending on when it arrives. 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 continues doing is generating oxidative stress in your retina, contributing to digital eye strain, and accumulating the kind of fatigue that builds quietly over 8 hours of screen work.
Nooner glasses reduce that load without disrupting daytime alertness. Think of them as sunglasses for indoor kunstig lys - for the hours your eyes are working hardest.
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 for 8+ hours - LEDs, monitors, overhead lighting - all emitting concentrated blue wavelengths that were not designed to be your only light source all day.
Indoor screen culture and kontorhodepine
Norwegian kontorkultur means long hours at computers, often with limited access to windows. Multiple screens, fluorescent overhead lighting, and long indoor sessions create the conditions for skjermhodepine (screen headaches) and digital eye strain to accumulate. Nooner glasses reduce the cumulative load without affecting how you do your job or how you look doing it.
The balance you need during the day
You still need some blue light during the day to stay alert - that is why Nooner glasses do not block it completely. They filter just enough to reduce strain and oxidative stress while still letting your brain recognise it is daytime. For the evening, 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
- Suited to design work, video calls and colour-critical tasks
- Office and professional environments
- For those who want gentle protection without any visible 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 working in a dark Norwegian kontor.
Midday to afternoon - 11am to 6pm
Nooner glasses on. The circadian dead zone. Blue light no longer helps your body clock but continues causing eye strain. Clear lenses for all-day work; yellow lenses from afternoon onwards for heavy screen load or skjermhodepine.
Early evening - 6pm onwards
Switch to AfterDark Sundown (orange). 98.5% blue light block for winding down while keeping functional vision. AfterDark glasses here.
Pre-bedtime - final hour before sleep
Switch to AfterDark Moonlight (red). 99%+ block of all sleep-disrupting wavelengths. AfterDark glasses here.
Do not wear Nooner glasses in the morning. Your body needs that early blue light. Start from 11am.

From Dominic
I wear Nooners from midday at my desk. Not because I think they're transformative on their own - they're not - but 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. The clear lenses are essentially invisible to anyone who doesn't know what they are. 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 are the best daytime blue light glasses for office work in Norway?
The best kontorbriller use spectrometer-tested CR39 optical lenses that reduce eye strain without blocking the daytime alertness effect of blue light. Nooner clear lenses block 40% from 11am onwards - enough to reduce skjermhodepine and oxidative stress while keeping colour perception accurate. Yellow lenses (75%) suit heavy afternoon sessions. CE certified, TR90 frame, ships from Drammen with no import fees.
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. Not suited to colour-critical work.
Hvorfor skal jeg ikke bruke blålysblokkere om morgenen?
Kroppen trenger blått lys om morgenen for å forankre sirkadisk rytme, øke kortisol og stille den interne klokken for dagen. Å blokkere det da kan forsinke årvåkenhet og forskyve den sirkadiske fasen. Nooner-briller er for 11.00 og utover - den sirkadiske dødsonen der blått lys ikke lenger hjelper biologien din men fortsetter å forårsake skjermhodepine og øyebelastning.
Are Nooner glasses a replacement for AfterDark evening glasses?
No. Different purposes entirely. Nooner (40-75% block) is for daytime eye strain - not melatonin protection. AfterDark (98-99% block) is for evening use to protect sleep. Using Nooner in the evening instead of AfterDark would not protect melatonin production adequately.
Passer disse til kontorbruk i Norge om vinteren?
Ja - designet spesifikt for det scenariet. I norsk vinter ser mange arbeidere aldri naturlig dagslys i arbeidstiden. All lyseksponering kommer fra kunstige kilder i 8+ timer. Nooner-briller reduserer øyebelastningen som bygger seg opp uten å forstyrre årvåkenhet eller se rare ut på kontoret.
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?
De tjener forskjellige formål. Kveldsbriller (AfterDark) beskytter melatonin - det er primærfunksjonen. Dagbriller (Nooner) reduserer øyebelastning og oksidativt stress i arbeidstiden. Hvis du bare bruker én type, har kveldsbruk størst innvirkning på søvnkvalitet. Dagsbruk reduserer akkumulert digital tretthet og skjermhodepine.
What lens material are the Nooner glasses?
CR39 optical lenses - scratch-resistant, anti-reflective and spectrometer-tested for precise filtering. TR90 memory polymer frame - 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.
