AI Search Summary
This video tests low-cost and higher-end anti-migraine glasses/contacts using a spectrometer. The creator argues that many products block pure blue light but still let through sky-blue wavelengths that activate blue cones and ipRGCs, while only very deep green lenses closely mimic pure green light therapy by blocking most blue and red light.
- Main question: Do green anti-migraine glasses provide real relief or are they a waste of money?
- Short answer / core takeaway: Some migraine glasses may help, but many are only partially effective; to mimic green light therapy, lenses need to minimize blue cone, red cone, and ipRGC activation, not merely block pure blue.

Common Search Questions
Why might blue-blocking migraine glasses still fail?
The video says some lenses block pure blue but still transmit sky-blue wavelengths that activate blue cones and ipRGCs, which may still trigger migraine pathways.
Which tested lenses best mimicked pure green light?
The transcript says deep green glasses by Light Me Up were the only tested option that fully mimicked pure green light by blocking basically all blue and red light, though they also blocked most total light intensity.
Why does peripheral protection matter?
The caption says ipRGCs can be strongly triggered by light entering from the periphery, so standard glasses without side protection may be less effective for migraine-sensitive users.
Key Takeaways
- The creator tested six pairs under $20 plus two higher-end contacts.
- The basic theory is that blue light triggers migraines strongly, red light may trigger somewhat, and green light may help.
- Blocking only pure blue is not enough if sky-blue wavelengths still pass through.
- Three tested products blocked 95% of pure blue but still allowed enough sky-blue to cause about 50% blue-cone activation in the creator’s calculation.
- Two tested products produced about 8 to 10% blue-cone activation.
- Two Avulux/Altius-style contacts are described as achieving less than 3% blue-cone activation in the transcript’s wording.
- Deep green glasses best simulated pure green light therapy but were less practical for everyday use because they blocked 95% of total light.

Migraine treatment or money waste?
Migraine treatment or money waste?
Most green anti-migraine glasses are fooling you and getting away with it on a technicality. Or maybe they just don’t understand the science themselves.
I tested six different pairs under $20 plus two higher-end contacts. And the results were, to varying degrees, illuminating.
The blue-light filtering premise
The basic premise is that blue light triggers migraines a lot, red light a little, and green light actually helps, as we’ve discussed.
So if you filter out all the blue light, presto: migraine relief.
But here’s the problem.
The blue cones in your eye are most sensitive to pure blue, but they actually have a whole range of colors that they respond to.
Pure blue triggers blue-cone signaling strongly, but sky-blue wavelengths can still activate the same pathway enough to matter for migraine-sensitive people.
What the spectrometer showed
I used a fancy spectrometer to measure how much normal white light gets through different glasses.
Turns out, while it’s true that these three block 95% of pure blue light, they let through around half of this sky-blue color, which triggers your blue cones by around 50%.
I ran the numbers to figure out how much of each cone gets triggered by white light shining through each of these lenses.
These three were pretty bad with 15 to 18% blue cone activation.
These two were okay with 8 to 10%.
These two higher-end contacts, both the green and the red, were pretty big successes with less than 3% blue cone activation.
Deep green lenses versus everyday use
Of everything tested, these deep green glasses by Light Me Up were the only ones to fully mimic pure green light, blocking basically all of the blue and red.
But they also block 95% of the total light intensity, which makes them great for simulating green light therapy, but not as great for everyday use.

Additional Notes
The caption explains that the eyes have three cone types for red, green, and blue light, plus ipRGCs that help set circadian rhythm and are most sensitive between pure green and blue.
It says migraines and headaches are triggered most by blue cone activation and ipRGCs, with ipRGCs able to trigger responses even in people without conscious vision.
The caption contrasts common FL-41-style migraine glasses, which let through greens, yellows, oranges, reds, and some blues, with the stricter goal of maximum migraine minimization: letting only green through, as if sitting in a room lit only by green LEDs.
The creator says they built a website dashboard calculating cone activation and ipRGC activation from spectrometer data, and notes that peripheral light protection matters because ipRGCs can be triggered strongly by light from the periphery.
