AfterDark Smooth - Blue Light Blocking Glasses for Sleep
CE-certified TR90 frames, metal inserts, CR39 optical lenses - spectrometer-tested and personally verified.
Blålysbriller med TR90-ramme og optiske CR39-linser - spektrometertestet for reell melatoninbeskyttelse
What these actually do - and why Night Shift doesn't
Your body produces melatonin in response to darkness. Specifically, it stops suppressing melatonin when the blue and cyan wavelengths around 480nm disappear from your environment. Screens, LED bulbs and overhead lighting all emit strongly in this range, which is why you can feel tired at 9pm and still not fall asleep until midnight - your retina is still reading it as daytime.
Night Shift and dark mode shift colour temperature slightly but don't block these wavelengths. Independent spectrometer tests put Night Shift's blue light reduction at roughly 20-30%. The AfterDark Sundown Orange lens blocks 98.5%. That gap is the difference between feeling vaguely less tired and your melatonin actually rising on schedule.
AfterDark Smooth uses CR39 optical lenses in a featherlight TR90 memory-polymer frame. Wear them from early evening while watching TV, reading or working on screens. Your body does the rest.
TR90 frame - what it means in practice
- Featherlight - weighs almost nothing; easily forgotten after a few minutes of wear
- Memory polymer flex - bends under pressure and returns to shape; survives being sat on, dropped or tossed in a bag
- Hypoallergenic - no nickel, no latex, comfortable against sensitive skin or during long evening sessions
- Metal inserts at hinges - reinforced joints where flex frames typically fail
- Contemporary profile - works as everyday eyewear, not just an evening wellness accessory
Two lens options - choose by when you use them
Sundown - Orange lens
- Blocks 98.5% of blue light and 95% of cyan wavelengths
- Designed for early to mid evening - dinner, screen work, social settings
- Maintains reasonable colour visibility for activities involving other people
- Ideal from 2-3 hours before your target sleep time
- The right starting point for most people - and the one Dominic recommends first
Moonlight - Red lens
- Blocks over 99% of blue and green light across 380-550nm
- Maximum melatonin protection - for the final 60-90 minutes before sleep
- Essential for Norwegian summer nights with daylight past 10pm
- Colour perception is significantly altered - for relaxed pre-sleep use only
CR39 optical lenses - why lens material matters
- Optically superior clarity compared to standard polycarbonate - less distortion at the periphery
- Scratch-resistant coating for lasting durability through regular evening use
- Spectrometer-tested for precise and verified light-blocking performance
- Thinner profile than polycarbonate at equivalent blocking performance

Why AfterDark
What's included
Norwegian summers and dark winters - both seasons need them
Summer: the sun stays up past 10pm, outdoor daylight keeps melatonin suppressed late into the evening, and screens in bright rooms compound it further. Moonlight lenses are essential. Winter: you are under artificial LED lighting for 16+ hours a day and the blue spike from those lights suppresses melatonin just as effectively as sunlight - even in complete outdoor darkness. For anyone dealing with mørketid, Sundown lenses from late afternoon, every evening through winter, is the most practical intervention available. Read more on the connection between light, melatonin and circadian health.
Complete the sleep environment
- Daytime screen work: Nooner daytime glasses - yellow lenses that reduce eye strain without blocking the alerting effect of blue light during hours you need it. AfterDark covers evening; Nooners cover the day.
- For children: AfterDark Kids glasses - same spectrometer-tested lenses in Starlight and Firefly frames sized for children. Children's eyes transmit 40-50% more blue light than adults.
- Room lighting: Sirkadisk belysning - amber and red evening bulbs that remove blue light from the whole room, not just what reaches your eyes through glasses.
- Nighttime navigation: SleepGuard amber night light - motion-activated 1800K amber for the bathroom and corridor so you don't undo the glasses' work at 3am.
- All blue light blockers: Full blålysbriller collection - all ten adult frames plus kids' models.
From Dominic
The Smooth frame is the one I would recommend if you want something you can genuinely forget you are wearing. The TR90 flex and the weight together make them disappear after a few minutes. Start with Sundown and wear them from dinner time - most people notice they feel sleepier at their normal bedtime within a few days of consistent use. Moonlight is for the last hour or for Norwegian summer evenings when the sun will not cooperate. If you are in Norway and dealing with mørketid, the Sundown lens from late afternoon every day through winter is the single highest-impact change most people can make to their sleep.

Frequently asked questions
What are the best blue light blocking glasses for sleep in Norway?
The best blålysbriller for søvn use spectrometer-tested lenses blocking at least 98% of blue light around 480nm. The AfterDark Smooth blocks 98.5% (Sundown Orange) or 99%+ (Moonlight Red), is CE certified, and ships from Drammen with no import fees. Verified with spectrometer data rather than manufacturer claims alone.
Are these better than Night Shift or dark mode?
Yes, significantly. Night Shift reduces blue light by roughly 20-30% and only affects your screen. The AfterDark Sundown Orange lens blocks 98.5% of blue and 95% of cyan from every light source - screens, LED bulbs, overhead lights. For actual melatonin protection in the evening, there is no comparison.
Sundown or Moonlight - which should I start with?
Sundown for most people. Wear them from 2-3 hours before bed, every evening. Add Moonlight for the final 60-90 minutes if you want maximum protection, or use Moonlight exclusively during Norwegian summer when evenings stay bright until late.
When should I start wearing them?
Sundown lenses: 2-3 hours before your target bedtime. Moonlight lenses: final 60-90 minutes. During mørketid, wearing Sundown from late afternoon every day protects your melatonin window even though it is dark outside - indoor LED lighting suppresses melatonin just as effectively as sunlight.
What are CR39 lenses and why do they matter?
CR39 is an optical-grade polymer that produces less peripheral distortion than standard polycarbonate. For glasses worn for extended evening periods, less distortion means less eye fatigue. Combined with spectrometer-verified filter performance and scratch-resistant coating, they are the professional-standard choice.
How are these different from cheap blue light glasses?
CE certification, spectrometer-tested blocking percentages, CR39 optical lenses, and TR90 memory-polymer frames with metal-reinforced hinges. Many low-cost alternatives claim blocking without verified test data. The comparison table above covers the key differences.
Are these useful during Norwegian mørketid?
Yes. During mørketid the problem is not the sun - it is indoor LEDs used for 16+ hours a day. Standard LED lighting still emits the blue wavelengths that suppress melatonin even in complete outdoor darkness. Sundown lenses from late afternoon, every day through winter.
Hva er de beste blålysbrillene for søvn i Norge?
De beste blålysbrillene for søvn bruker spektrometertestede linser som blokkerer minst 98% av blått lys. AfterDark Smooth blokkerer 98,5% (Sundown Orange) eller 99%+ (Moonlight Red), er CE-sertifisert og leveres fra Drammen uten importavgifter.
Er blålysbriller bedre enn Night Shift pa iPhone?
Ja, vesentlig. Night Shift reduserer blått lys med omtrent 20-30% og kun pa skjermen din. AfterDark Sundown Orange-linsen blokkerer 98,5% av blatt og 95% av cyan fra alle lyskilder - skjermer, LED-pærer, taklys. For reell melatoninbeskyttelse om kvelden er det ingen sammenligning.
Nar bor jeg begynne a bruke blålysbriller om kvelden?
Sundown-linser fra 2-3 timer for planlagt leggetid. Moonlight-linser de siste 60-90 minuttene. Under mørketid beskytter Sundown brukt fra tidlig kveld melatoninvinduet selv i fullstendig utendørs morke - innendørs LED-belysning undertrykker melatonin akkurat like effektivt som sollys.
