Scientific research proves the effectiveness of the PROPEAQ light therapy glasses
Light guides your rhythm. Rhythm shapes your day and night.
Light is the forgotten force that governs our day–night rhythm. It wakes us at sunrise, calms us in the evening, and keeps us in balance. When that rhythm becomes disrupted, light can help restore the body’s natural biorhythm.
In the 1980s, this insight led to the development of light therapy: by applying the right light at the right time, you sleep better, feel more energised, and recover faster.
PROPEAQ inventor Toine Schoutens has been involved from the very beginning as a researcher and light specialist. Where light therapy once required large lamps, he developed the first wearable light therapy glasses in 2007. Their effectiveness was soon proven in elite sport, from Olympic swimmers to cyclists and racing drivers, all using light to perform at their peak at precisely the right moment.
Beyond elite sport, Toine has worked closely with leading researchers, including Prof. Dr Bas Bloem (Parkinson’s disease) and Prof. Dr Sandra Kooij (ADHD). Multiple clinical studies using the PROPEAQ glasses have shown impressive results.
The conclusion is clear: the PROPEAQ light therapy glasses help you regulate your biorhythm. The results: Better sleep More daytime energy A more stable mood
Light therapy has proven to be not a hype, but a source of hope for everyone affected by Parkinson’s

People with ADHD often experience a disrupted sleep pattern and a delayed biological clock. Research using blue light in the morning, emitted by the PROPEAQ light therapy glasses, shows that we can better regulate the day–night rhythm, leading to greater calm, improved concentration, and fewer ADHD symptoms during the day.

How does our biorhythm actually work?
Our body follows a 24-hour rhythm, also known as the circadian rhythm or sleep–wake cycle. And the main driving force? Light.
In the morning, daylight triggers the production of cortisol, helping you start the day feeling energised and alert.
Throughout the day, daylight also supports the production of serotonin, the happiness horm that keeps your mood and focus stable.
As darkness falls, your body begins to produce melatonin. This hormone makes you feel sleepy and promotes deep, restorative sleep.
In this way, light gives you energy and concentration during the day, while darkness at night allows your body to rest and recover. When this rhythm is disrupted, e.g. by jet lag, irregular work shifts, excessive screen time, or other factors, your sleep and energy levels can quickly fall out of balance.
With the right light at the right time, you can reset your biorhythm, for more energy during the day and a better night’s rest.
