A Closer Look at the Best in Light Therapy: retimer 3, Luminette 3, and Ayo

retimer 3, Luminette, and AYO all use light therapy to help us sleep better and feel more energized, but which one is the right fit for our lifestyle? 

Light therapy glasses have transformed the way we address sleep challenges, seasonal affective disorders, and circadian rhythm disruptions. 

These innovative wearable devices deliver light exposure while we maintain our daily routine, freeing us from the constraints of traditional stationary light boxes. 

In the landscape of light therapy glasses, three excellent brands stand out: retimer 3, Luminette, and Ayo. Each offers a unique approach to light therapy with its own merits. In this comparison, let’s see how retimer 3, Luminette & Ayo stack up in terms of effectiveness, comfort, design, and more, so we can find the perfect fit for our lifestyle. 

The Science Behind Light Therapy GlasseProfessional Endorsements and Clinical Recognitions 

Studies have shown that exposure to light at different times of day can alter the timing of the body clock and sleep-wake patterns. Bright light in the morning can retime our body clock, making it easier to fall asleep at night and wake up earlier in the morning. On the other hand, exposure at night can delay the time we fall asleep and prolong our wake-up time the next day. 

Light therapy glasses are wearable devices that deliver carefully calibrated light directly to our eyes to regulate our circadian rhythm.

These devices work by suppressing melatonin production during the day and boosting serotonin levels, helping regulate our sleep-wake cycle, improve mood, and increase energy levels. The key advantage of glasses over traditional light boxes is mobility. Since the glasses are at a fixed distance from our eyes, we can receive light therapy while reading, working, exercising, or performing other daily activities. 

How to Choose the Right Device 

Picking the right light therapy glasses is the key.  
The right device delivers effective results, ensures your safety, and provides ease of use.  

Here’s what to keep in mind when making your choice: 

• Effectiveness: 
  Our body responds to specific light intensity and wavelength. The intensity should not be low, high, or off-target; it won’t get you the right results. That’s why clinically proven wearables have efficacy. 

• Safety: 
  Incorrect intensity can be harmful to the eyes. Light therapy glasses should deliver precise intensity and wavelength, powerful enough to work, safe for daily use, and crucially, flicker-free. 

• Comfort: 
  If the glasses are being worn for 30–60 minutes a day, then comfort counts. Look for something lightweight, portable, and with a soft nose piece to make it more likely to stick with a routine. 

• Durability: 
  Choose a pair that feels solid and built to last, ideally backed by a warranty. Quality construction means better value and consistent performance over time. 

• Preference: 
  Our needs are unique, whether it’s jet lag, winter blues, or sleep issues. Choose glasses that offer customizable schedules to match our specific requirements. 

The Top 3 Light Therapy Glasses 

retimer 3

retimer 3 is the latest innovation from Re-Time Pty Ltd, a sleep technology company based in Adelaide, Australia. In 2010, the company made history by launching the world’s first medically certified light therapy device specifically designed to address circadian rhythm disorders.  
 
retimer 3 builds on this legacy and was successfully introduced in 2024 through a successfully supported crowdfunding campaign on Kickstarter. Backed by over 25+ years of scientific research led by world-renowned sleep expert Professor Leon Lack from Flinders University, retimer 3 reflects a deep commitment to clinical effectiveness and innovation. 

Scientific Foundation 

retimer 3 has a distinct advantage with a foundation built on decades of sleep science research. The design is developed through extensive clinical trials and peer-reviewed research. A team of sleep psychologists, ophthalmic experts, and engineers has worked meticulously to create a device that aligns the circadian rhythm while ensuring safety and comfort.  

Optimal Below-the-Eye Light Delivery 

retimer 3’s below-the-eye light delivery allows for unobstructed vision and is designed for seamless use over prescription glasses, enhancing practicality without compromising effectiveness. 

Why Below-the-Eye Delivery Excels: 

• Unobstructed Light Path: The bottom-up light delivery approach ensures consistent, evenly distributed exposure across different facial structures, maintaining efficacy while keeping vision unobstructed. 
• Natural Eye Movement Integration: Since daily activities often involve downward gaze (reading, computer use, or other chores), retimer 3’s design aligns with natural eye movements, ensuring optimal light exposure. 
• Superior Prescription Glasses Compatibility: The under-eye approach is compatible with all prescription glasses styles.  

Blue-Green Light Technology 

retimer 3’s 500nm blue-green light represents the gold standard in wavelength selection: 

• Enhanced Safety Profile: The 500nm wavelength provides powerful circadian activation while being gentle on the eyes, making it suitable for extended daily use without discomfort. 
• Sustained Long-Term Effectiveness: Research demonstrates that the 500nm wavelength provides more sustainable long-term results with user compliance due to its comfortable profile. 
• Scientifically Validated Precision: The specific wavelength was selected based on detailed research into human circadian photoreception, representing the optimal balance of effectiveness and safety. 

App Integration 

retimer 3’s mobile app is designed for the best outcome from the device based on lifestyle needs. 

Advanced Personalized Scheduling: The app offers tailored scheduling options to suit a variety of needs, helping us get the most out of our light therapy. These include:
