An unregulated internal clock often leads to poor sleep, low energy, daytime sleepiness, and winter blues. Light therapy glasses have become a popular and effective treatment for ensuring your internal clock is in sync.
AYO and Luminette 3 are two of the leading light therapy devices on the market. This comparative review is all you need to decide which to get.
As a first mover, the Luminette is battle-tested and has seen different upgrades and iterations. It features a patented light delivery system that indirectly supplies light into your eyes to reduce glare. On the other hand, AYO shines with its sleek design and more stylish look.
This Luminette and Ayo glasses review explores their design, technology, key features, and overall effectiveness to help you choose the right one for your needs.
Overview of light therapy glasses
Light therapy glasses are devices that emit light with specific qualities such as wavelength, light intensity, and colour. These devices are also known as happy light and are prescribed for treating various conditions, such as:
Winter and autumn blues scientifically called seasonal affective disorder (SAD)
Jet lag
Low energy
Sleep disorders and insomnia
Shift workers' productivity
Mood and anxiety disorders
You wear these devices like you would regular glasses. The light from the glasses enters your eyes and signals to your brain that it's daytime.
The mood improvement glasses work by mimicking the effects of the sun, with the primary aim of resetting the body's internal clock. The internal clock regulates activities such as sleep and wakefulness, and this is the basis for every other benefit.
A healthy or properly calibrated internal clock ensures the body releases the right hormones and chemicals when due.
For example, an in-sync body clock will aid the production of certain chemicals called neurotransmitters like norepinephrine, histamine, and serotonin in the morning so that you wake up refreshed .
Your body produces more melatonin in the morning when your internal clock is out of sync due to a lack of light. This causes you to feel lethargic, moody, and sleepy throughout the day.

Importance of choosing the right light therapy device
Safety
The first step is to ensure the device does not emit harmful UV radiation to prevent skin damage around the eyes and irreparable eye issues.
In that light, choose devices with certifications from reputable organisations like the CE markings and IEC 62471 standard.
For example, if sold in Europe, the device should carry the CE marking like the Luminette. The CE marking indicates that the device has been tested for safety and judged to meet the required safety standards.
Efficacy
Consider only devices that emit a specific spectrum of light tailored to your needs. Different wavelengths of light have different effects.
Research shows that light with short wavelengths (∼460–480 nm) produces the best results regarding improving alertness and cognitive function.
More importantly, only opt for devices backed by scientific research and clinical trials showing their effectiveness for your desired need.
In addition, read user reviews across multiple platforms to gain insights about the device from people who have actually used it.
Comfort
Most light therapy sessions last 20-45 minutes, depending on the light intensity configuration. To this end, choose a device that fits comfortably and doesn't cause discomfort during use.
Such devices come with an ergonomic design, are thin and light, and are crafted to emit light from an eye-safe distance.
Practical features
Devices that offer features like timers and adjustable light settings make sessions easier for users and more personalised.
On a similar note, ensure the device is easy to use and made from high-quality materials built to last.
Light Therapy by Luminette 3
In 2002, researchers from the sleep medicine and optical physics departments at the Université de Liège (Belgium) imagined and worked towards a light therapy device that doesn’t interrupt the user’s activities.
After four years of research, prototyping, designing, and testing, the first Luminette was released. The Luminette 3 is an upgrade of the two previous versions of this product.
Below, we explore Luminette 3 benefits and key features.
Key Luminette 3 features
Patented Light Technology
The Luminette 3 uses a patented optical technology that directs blue-enriched white light into your eyes from top to bottom without blocking your vision.
This device uniquely uses a 'hologram' lens. Instead of shining directly into your eyes, the light bounces off a mirror-like surface and then is gently directed toward your eyes. This design eliminates glare, a prominent eye concern experienced by users of most light therapy devices.
Short wavelength light
The device emits blue light with a wavelength of 468 nm, designed to mimic sunlight and regulate the body's circadian rhythm, and has proven to be the most effective at rejuvenating the body and mind.
Some blue light benefits include increased alertness, improved energy, and a healthy internal clock.
Adjustable light intensity and timer
The Luminette light therapy glasses have three light intensities: 500, 1000, and 1500 lux. This flexibility allows users to choose the intensity they’re comfortable with and get familiar with the device initially by using a lower light intensity.
The timer is both a safety and personalisation feature. You can set the timer so the device goes off automatically when the time elapses. This prevents eye issues from device overuse.
Rechargeable battery
The device comes with a rechargeable battery that can last 5-10 light therapy sessions, depending on the light settings. The battery can be recharged using the device's micro-USB cable and US plug charger.
Ergonomic nosepad
The Luminette also features an ergonomic nose support that ensures the device feels snug and doesn't fall off. It comes with extra nose pads, too, for when the current one wears and tears.
Portable and practical
The Luminette 3 is a compact, lightweight device weighing only 51 grams. You can literally forget it on your face. This compactness also makes it a great travel companion to beat jet lag and adapt to new time zones. There’s also a nice travel case to protect your device in transit.
Safe and certified
The Luminette carries the CE badge and is compliant with the international standard IEC62471, which classifies the device as "risk-free" for the eyes.

Benefits of using Luminette 3 for light therapy
Improved Sleep Quality
In an independent study that evaluated the effect of using the Luminette on the delayed sleep phase syndrome, a condition where people sleep later and wake up later than expected, the researchers found that 68% of participants in the trials improved their sleep quality (longer sleep duration, falling asleep quicker, and reduced daytime sleepiness).
Higher energy levels
It doesn’t matter if you’re enduring low energy levels from sleep deprivation or as part of winter fatigue symptoms ; the Luminette can help.
One clinical trial that studied the effects of the Luminette on employees working in a Radiotherapy department without access to light concluded that “the levels of daytime slumber or slothfulness significantly decreased.”
The researchers also found that these benefits persisted one month later without light therapy for sleep, showing the near long-term effect the Luminette has on overall well-being.
Increased alertness and sharpness
Researchers in another trial found that participants who had light therapy sessions with the Luminette before a psychomotor vigilance task performed better and had lower reaction times (lower is good).
The researchers concluded that the Luminette elicits the same effect as standard bright light therapy boxes.
Better morale or mood
Beat winter blues and other symptoms of deep sadness with consistent light therapy sessions using the Luminette 3.
In a clinical trial with participants diagnosed with deep feelings of sadness, the researchers exposed one group to bright light therapy with the Luminette.
The analysis showed that “depressive symptoms, sleep problems, and the global clinical impression improved significantly” in the bright light therapy group.
Safe light therapy sessions
Light emitted from the Luminette 3 is free from harmful infrared and UV rays. This device has also received the highest safety badge by meeting the bar set by the IEC 62471 standard. The Luminette 3 is safe to use and 100% risk-free.
Luminette 3 light therapy glasses are innovative eyeglasses designed to allow you to enjoy a light therapy session while engaging in your regular activities. Unlike traditional therapy lamps, Luminette 3 eyeglasses feature an artificial light source that directs a safe light beam into your eyes without causing any dazzling effect or obstructing your clear vision.
To use them, simply wear the eyeglasses and press a button to activate the light, and your phototherapy session begins. These glasses are user-friendly and compatible with those who wear prescription glasses or contact lenses, ensuring no disruption to vision or comfort.
With the convenience of Luminette 3, there is no longer a need to sit beside a stationary light therapy lamp for 30 minutes each day. The freedom to move around means you can prepare breakfast, dive into a captivating book, catch up on your favorite TV shows, work on your computer tasks, or even engage in light exercises, all while receiving your therapeutic light exposure. Whether you're at home or on the go, Luminette 3 offers a flexible and efficient solution to incorporate light therapy into your daily life.
AYO light therapy glasses
AYO light glasses entered the market in 2015 as a wearable solution designed to help individuals regulate their body clock and improve their mood.
