Books, screens, small print, early starts. If your day happens within arm's reach, this was built for you.
Newspapers, novels, crosswords. Ten minutes before you sit down with them.
Laptop, phone, tablet. A real break between the calls, not another scroll.
Daylight-style blue light with your first coffee. Duo model only.
50g and folds flat. It lives in the laptop bag, not the suitcase.
Red light for your eyes. Blue light for your rhythm. Choose one, or get both.
A gentle, low-level deep red wavelength that has been widely studied for its role in supporting the body's natural cellular energy processes. UV-free and non-invasive, it's designed for everyday visual wellness — a short, hands-free session that fits between meetings, or before you sit down with a book.
Included in MEINNO Red and MEINNO Duo
A daylight-style wavelength commonly used to support alertness and circadian rhythm alignment. Morning light exposure is a long-established habit among people managing jet lag, shift work, or the darker months of the year.
MEINNO Duo only
Backed by published research
Our wavelengths weren’t picked for how they look. They come from peer-reviewed research at University College London and the University of Manchester.

Comparison based on publicly listed prices and specifications of leading clinic-style 670nm red light glasses, October 2026. Features and terms vary by brand and model. MEINNO is a general wellness device and is not intended to diagnose, treat, cure or prevent any disease.
An open frame, a folding hinge, and nothing sitting in front of your eyes.
A faceted white shell with a soft chamfer running the length of the front. It reads as a personal object, not hospital equipment.
No lenses, no glass, no closed visor. The frame sits above the brow on a soft rubber bridge, so your view stays completely open.
The blue silicone arms fold in against the body. It goes in the laptop bag, the carry-on, or the bedside drawer.
The open frame clears most prescription and reading glasses. You don't have to take anything off to use it.
In the box
No accessory upsells, no "pro bundle". The strap and the spare bridge are in every box, because some heads need them and we'd rather not make you guess.
No app, no pairing, no setup. One button does everything.
Over your reading glasses if you wear them. The rubber bridge rests on your nose, the arms hook over your ears.
One button cycles ten, fifteen or twenty minutes. Brightness eases up over the first sixty seconds.
Read, listen to something, or just sit back. It shuts itself off when the timer ends.
670nm light has been studied in peer-reviewed literature for two decades. We list the papers, label what kind of study each one is, and link straight to them.

A clinical device from another manufacturer — not MEINNO
These studies examine 670nm light in general. They were conducted with research-grade equipment at specific doses and do not describe the performance of this product.

MEINNO has no affiliation with, and is not endorsed by, any institution or journal named above.
Honest expectations
No miracle timeline. Just what using it is like, and what to do if it isn't for you.
Brightness eases up over sixty seconds. Most people forget it's on within a few minutes and go back to their book.
Ten minutes goes next to something you already do — the first coffee, the morning news, the inbox. That's what makes it stick.
Some people describe a difference by now; others don't. Either answer is useful, and both are allowed.
You can send it back for a full refund any time up to day ninety. We cover the return shipping.

480nm Blue
Daylight White
A different kind of light
MEINNO Dawn swaps the red light for a bright blue-and-white daylight spectrum, in the same frame you already know. Two modes, because people respond differently to each — try both and keep the one that suits you.
Including the ones with answers you might not expect.
No. MEINNO is a general wellness product designed for relaxation and everyday comfort. It is not registered or marketed as a medical device, and it makes no medical claims.
No. Presbyopia is caused by natural changes in the lens of the eye, and no light-based device can reverse that — you'll still need your reading glasses. What many people in this age group are looking for is simply a comfortable break during long stretches of close-up work, and that's what MEINNO is designed for.
Yes. It uses gentle, low-intensity, UV-free light, and brightness increases gradually over the first sixty seconds so your eyes adapt comfortably. That said, if anything feels uncomfortable, stop and take a break.
Yes. The open frame sits above the brow and clears most prescription and reading glasses. Very large or thick frames may be a tighter fit.
Every MEINNO ships with an adjustable sport strap. Clip it to both arms and the frame holds securely whether you're lying back, walking around the house, or on the treadmill. A spare nose bridge is included in the box as well.
The glasses, a zip travel case, an adjustable sport strap, a spare nose bridge, a USB-C charging cable and a user manual.
For red light, ten to fifteen minutes a day. Mornings are best, but any time of day works. For the blue mode on MEINNO Duo, twenty to thirty minutes in the morning or during the day — not in the evening, because it's meant to help you feel alert. More is not better.
Talk to your eye care professional first. MEINNO is not designed to diagnose, treat, cure or prevent any condition, and it is not a substitute for an eye examination.
Send it back within ninety days for a full refund. You don't need a reason.
