(Runde blålysbriller med TR90-ramme og UV400 - testet med spektrometer)
Why the frame shape matters as much as the lens
Most blue light glasses leave a gap at the sides. The Quantum's wider round lens profile wraps closer to the face, which means less peripheral light bleed around the edges, the stray ceiling light that slips past a narrow frame and still hits your retina.
The TR90 frame is light enough to forget you're wearing them. That matters for something you put on every evening for two to three hours. Pair that with spectrometer-verified Amber or Red lenses and you have a glasses setup that actually does what it claims. Read more about why blue light affects more than just your eyes - the biology runs deeper than most people realise.
TR90 frame — the practical details
- Round retro profile — wider lens area for better peripheral coverage than narrow square frames
- Memory polymer flex — bends without snapping; survives being sat on or dropped
- Featherlight — typically forgotten within a few minutes of wearing
- Hypoallergenic — no nickel, suitable for sensitive skin and extended evening wear
- UV400 certified — full UV protection built in
- Frame size: 47mm lens, 24mm bridge, 149mm temple — fits most adult face shapes
Two lenses — choose by time of evening
Amber lens — 97% blue light blocked
- Covers the 380–500nm range where melanopsin activation is highest
- Maintains reasonable colour visibility - reading, watching TV, general indoor use
- Start wearing 2–3 hours before your target bedtime
- The right choice for most evenings, most of the year
- Verified by spectrometer - not a manufacturer claim
Red lens — 99%+ blue and green light blocked
- Blocks across the full 380–550nm range, including green wavelengths that amber misses
- Maximum melatonin protection - for the final 60–90 minutes before sleep
- Essential during Norwegian summer when daylight runs past 10pm
- Colour perception is heavily altered - for relaxed pre-sleep use only
- Worth switching to earlier on nights when sleep quality really matters
What is actually happening in your eyes
Your retina contains melanopsin photoreceptors ( intrinsically photosensitive retinal ganglion cells) that respond specifically to short-wavelength blue and cyan light. When these cells detect blue light, they send a signal to the suprachiasmatic nucleus (your brain's central clock) indicating that it's still daytime. Melatonin release is suppressed as a result, even when you're tired and it's 11pm.
Blocking those wavelengths with Amber or Red lenses in the evening removes that false daylight signal. Your melatonin rises on its natural schedule. Most people notice they feel sleepier at their usual bedtime within a few nights of consistent use - particularly if they were previously scrolling on a phone right up until they turned the light off. For a deeper read, the circadian lighting collection covers how this extends to your room environment, not just your screens.
Why AfterDark Quantum
Norway runs on extremes - your glasses need to match
Summer: the sun is up past 10pm in Oslo and well past midnight further north. Outdoor daylight keeps melatonin suppressed late, and then you come indoors to LED screens and carry on. Red lenses are worth it from 8pm onwards during lysårstid.
Mørketid: it's dark outside from 3pm but you're sitting under full-spectrum LED bulbs until midnight. Those bulbs emit the same short-wavelength light as a summer sky. Your body has no way to know it's polar night from inside your apartment. Amber lenses from late afternoon, every evening through winter - this is the same principle behind circadian lighting but applied to your personal light environment.
What's in the box
The rest of the AfterDark range
Looking for a different frame style? The Smooth has a contemporary everyday profile, the Classic suits a traditional look, and the Meridian comes with four magnetic lens swaps covering every protection level from clear to red, the most flexible option if you want all-day coverage. For daytime screen work without affecting your morning alertness, the Nooner uses a yellow lens calibrated for daytime use.
From Dominic
The round frame on the Quantum gives better peripheral coverage than most of the narrower frames I carry, you notice the difference when you're sitting in a bright room rather than a dim one. If you're new to blue light glasses, start with Amber. Wear them from dinner time. Give it a week before you judge. Most people notice something within three or four nights - they just feel sleepier when they'd normally still be wired. Add Red for the last hour if you're a light sleeper or it's a Norwegian summer evening and the sun still hasn't fully cooperated.

Important — not for driving or machinery
Both Amber and Red lenses significantly alter colour perception. Do not use while driving, cycling on roads, or operating any machinery. These are indoor, stationary evening glasses.

Questions people actually ask
Amber or Red — which should I start with?
Amber for most people, most evenings. Put them on 2–3 hours before bed and keep them on. Add Red for the final hour or swap to Red only during Norwegian summer when evenings are still bright at 10pm. If you're a consistently poor sleeper, go straight to Red from dinner time and see if that makes a difference first.
Why does the round frame help more than a narrow one?
Blue light enters the eye from all angles, not just straight ahead. A wider round lens reduces the gap between the frame and your face at the sides, cutting down on peripheral light that slips past a narrow frame. It won't seal completely — these aren't wraparound goggles — but the difference in a bright room is real.
Hva er forskjellen mellom amber- og rødlinser?
Amber-linser blokkerer 97% av blått lys og egner seg for kveldstimer der du fortsatt beveger deg rundt og ser på TV. Røde linser blokkerer 99%+ av både blått og grønt lys — maksimal melatonin-beskyttelse for den siste timen før søvn, eller for norske sommerekvelder der dagslyset varer til langt på kveld.
Are these useful during Norwegian mørketid?
Yes — and arguably more so than summer. When it's dark outside but you're under bright LED lighting from 3pm to midnight, your melanopsin receptors can't tell the difference between that and a summer afternoon. The glasses handle the artificial light side; pairing them with low-blue circadian bulbs in your main living areas handles the ambient side.
Do the blocking percentages actually hold up?
Yes. The AfterDark range is spectrometer-tested across the full visible spectrum. Amber: 97% blue light blocked. Red: 99%+ blue and green light blocked. These are measured results, not marketing numbers copied from a supplier sheet.
Can I wear these over prescription glasses?
The Quantum round frame is not designed as an over-glasses fit. If you need prescription compatibility, contact Dominic directly at admin@lighttherapy.no and he can advise on which frame in the range fits over prescription glasses.
