Humanoids have been walking the earth for at least two million years, “modern” man has a history of some 200,000 years, and artificial light has only been influencing our existence for 300 years. Evolution has given us a complex body that adapts to its environment and bends it to its will. We can also influence the influence of day and night on our body.
The human body reacts to the blue tint of the morning light and the red which comes with sunset. At daybreak, all our internal systems start up. Once the sun goes down, our bodies start preparing for rest and sleep. Digestion and other body systems switch into night mode.
Anyone who deviates from the usual day-and-night rhythm, travels through multiple time zones or struggles with sleep deprivation due to an irregular existence may find that the body sputters against it. The day is no longer synchronized with the internal biological clock. These cannot always keep up with the rapid social and technological evolution of our existence.
Light therapy is the answer to this situation, based on the scientifically proven knowledge that the body gets energy when the eyes see the correct blue light. You can be your own enemy here, for example by wearing sunglasses for a long time and often that block blue light and thus reduce your energy. The Propeaq light glasses restore balance as the blue lenses dose the available sunlight. When there is no sun, the blue LEDs in the glasses give the body extra energy.
On the contrary, when the aim is to unwind and prepare for a good sleep, replace the blue lenses in the glasses with the orange ones easily clicked in. The orange glasses block all energy input from blue light, so the body responds with increased production of the sleep hormone melatonin. Propeaq light glasses are the only complete wearable system for optimal light therapy.
There are two Propeaq light glasses models. The effectiveness of both glasses is the same. The Basic model is substantially simplified from the Premium model (not currently available) in two respects.
The Propeaq light therapy glasses make it possible to apply sufficient blue light in 30 minutes per day. Those are 30 minutes in which the user can continue to work. The standard glasses have no prescription in the lenses. The amount of blue LED light is not a hindrance to good vision in normal ambient light. Use of contact lenses has no impeding effect.

Propeaq’s blue LED light has a wavelength of 468 nanometers at an intensity of only 215 M-EDI (measurement report available on request). The LEDs are 1.5 cm from the eye and are harmless under normal use*. One administration of 30 minutes of active blue light per 24 hours is often sufficient. The light glasses do not have to be worn continuously for a long time. For those already wearing glasses, there are solutions with clip-on glasses or even prescription lenses. Through a close cooperation with a renowned international operating manufacturer of eyeglass lenses, Propeaq glasses are also available in prescription form from specialized opticians
* In case of diseases of the retina, for example macular degeneration, we recommend using the light glasses. Not enough research has yet been conducted into possible harmfulness in these situations.
When to use light blue lenses? For extra energy!
The blue light in the glasses is used to simulate the sunlight in the morning. When using the blue light, we recommend using the slightly transparent/light blue lenses. However, this is not necessary. One can also choose not to use lenses in the frame when the blue light is on.
When to use orange glasses? To get drowsy.
The orange glass filters the blue light we see from daylight and some artificial light sources. Orange lenses are used in the glasses to stimulate the body’s natural production of melatonin. This natural hormone takes care of it drowsiness and is necessary for a good night’s sleep.
Note: When the blue light is turned on with the orange lenses in the frame, the filtering will not work. So only use orange glasses when the blue light from the glasses is off and you want to prepare the body for sleep.
You don’t have to do anything more than answer a few questions and choose your goal for light therapy. The app will give you tips for an optimal schedule with clear instructions for using your light glasses. Forgetful? The glasses as well as your phone will help you remember.
The included app provides all the personalized schedules for getting the most from your Propeaq glasses. The schedules and advice combine all experiences from scientific studies, the guidance of elite athletes and practical tests.
The apps are available for free in the App Store (iPhone) and Google Play (Android).
