About MEINNO
Seven Years on One Wavelength
We started in 2018 with a narrow question: could a specific band of light be delivered comfortably enough that someone would actually use it every day? Most of the years since have gone into answering it.
How we got here
MEINNO was founded in 2018. For the first few years we didn't sell anything. We read the literature, built prototypes, and spent an unreasonable amount of time on a problem most people never think about: getting an LED to sit close to someone's face, at a controlled output, without being heavy, hot, or awkward enough that it ends up in a drawer.
Light is easy to produce. Light at a specific, verified wavelength, at an output that stays consistent from the first unit to the ten-thousandth — that's the part that takes years. Every batch we ship is spectrally checked against the same reference, because a device that drifts to 690nm is not the device the research describes.
The frame you can buy today is our second generation, refined from everything the first one taught us: lighter, better balanced on the nose, and with a gentler sixty-second ramp so it never hits your eyes cold. It is not a medical device and we don't market it as one. It's a small, well-made object that gives your eyes ten minutes.
The Short Version
Four moments that matter.
2018
Founded
MEINNO is registered, and the first prototypes go on the bench.
2019–22
Development
Years of iteration on optics, output stability, weight and fit.
2023
First generation
The first wearable frame ships, and starts teaching us what to fix.
Today
Second generation
Lighter, better balanced, and tested to IEC 62471.
What We Hold Ourselves To
Three things we won't compromise on, because they're the only things that separate a real device from a red LED in a plastic frame.
Spectral calibration
Every production batch is measured against the same reference so the peak stays where it should be. A wavelength that drifts is a different product.
Independent safety testing
Tested to the IEC 62471 photobiological safety standard and classified in the non-hazardous group. UV-free across every mode.
We fix what we get wrong
The current frame exists because the first one had problems. Weight, balance and the start-up ramp all changed based on what customers told us.
Testing & Certification
We list exactly what we've been tested to, and nothing we haven't.
