Your body needs melatonin to start rising a few hours before sleep. Blue and cyan wavelengths from screens and LED lights block that signal — telling your brain it's still daytime even at 10pm. AfterDark glasses remove those wavelengths before they reach your eyes each evening, so your melatonin can rise on schedule without any other changes to your routine.
The range now covers ten frame styles across TR90 flex, metal, and kids' profiles. All share the same spectrometer-tested CR39 optical lenses. The choice is about fit and lifestyle — not protection level. Choose the frame you'll actually wear every evening.
The melanopsin-containing retinal ganglion cells in your eyes are maximally sensitive to light between 460–490 nm — exactly where blue LEDs and screens peak. Even dim evening light in the blue range is enough to suppress melatonin production by up to 50% and delay its onset by 90 minutes or more. AfterDark lenses physically block that band before it reaches the retina — the equivalent of telling your brain the sun has set, even if you're watching TV under bright LED ceiling lights.
This is why screen filters and "night mode" settings aren't sufficient on their own — they reduce some blue light but still allow significant transmission in the 460–490 nm band. Physical lenses blocking 98–99% of the relevant spectrum are a different order of magnitude.
From June to August the sky never gets properly dark. Even in Drammen and Oslo the evening light at 10pm is still bright enough to suppress melatonin. Moonlight red lenses become essential for sleep through Norwegian summer.
The trap is assuming glasses don't matter when it's dark outside. Indoor LED lighting emits the same 450 nm blue peak regardless. You can suppress your melatonin just as effectively in January under artificial light as in June. With your circadian system already under stress from the lack of morning light, adding evening suppression makes it significantly worse.
Children's crystalline lenses are clearer than adults', transmitting 40–50% more blue light to the retina. Evening screen time without protection significantly delays their melatonin onset. The Firefly and Starlight frames are sized specifically for smaller faces.
Most Norwegian homes run standard LED lighting that peaks strongly in the blue range. The most consistent results come from combining AfterDark glasses with amber or red bulbs at home — glasses handle screens, bulbs handle everything else.
All frames are available in both lenses. Choose based on when and how you wear them:
- Blocks 98.5% of blue light
- Blocks 95% of cyan wavelengths
- Colour perception shifted but functional
- Good for TV, screens, social settings
- Best from dinner until ~1 hour before sleep
- Blocks 99%+ of blue AND green light
- Full 380–550 nm spectrum blocked
- Colour perception significantly altered
- For the final 60–90 minutes before sleep
- Essential for Nordic summer nights

The glasses are the easiest entry point into circadian management. You don't need to change anything about your evening — just put them on when you sit down for dinner. Most people notice a real difference in how quickly they feel sleepy within three to five evenings of consistent use. That's not coincidence; it's what happens when your melatonin starts rising at the right time again.
These are the fourth generation of AfterDark glasses I've brought to Norway, and the one I'm most proud of. The frame quality, the lens accuracy, the range of options — kids sizes, metal frames, the Arc for those who want the Halo look with a more secure grip, the Phase Shift for those who want day-and-evening coverage in one frame, and the Meridian for those who want the complete picture. Each iteration has been driven by what customers actually asked for.
If you're not sure which frame to start with, just reach out. I'm still the one answering here in Drammen.
