FAQ – Frequent asked questions

How long do I have to wear the glasses?
The use of the glasses depends on the desired effect. With active blue light, 30 minutes per day is usually sufficient. If the red glasses are used, then half an hour to an hour before going to sleep is enough.
How do I switch the glasses on / off?

Press the on / off switch until the 3 blue LEDs light up. Release the button and wait until the 3 LEDs dim. Then briefly press the button twice and the blue light comes on.

Is an app necessary for the use of light glasses?
There are two apps by Propeaq that help with the correct use of light glasses. There is an app with personalized advice to prevent jet lag. Another app helps with night shifts. Both apps personalize advice based on data provided. The glasses do not communicate with the app and the data remains in the app and is not shared.
What information do I share with the makers of light glasses?
The glasses do not communicate with the app and the data remains in the app and is therefore not shared with the makers or others.

Is the light safe?
The blue light from the light glasses is very weak and in a bandwidth of which no harmful effects are known. The eyes may be lasered, wear contact lenses or be fitted with an artificial lens. Only people with a retinal defect (retinopathy) are not recommended for use because no research has been done on this.
Can I drive a car wearing the light glasses?
When the light in the glasses is on, we advise against participating in traffic in the dark. We also advise against taking part in traffic with the red glasses as a red traffic light then shows dark gray.
Why are there different colors of glasses in the box?
The Propeaq glasses are a complete system with active light for energy and red glasses for better sleep. The dark blue glasses can be used as sunglasses and reduce the amount of light, but let the healthy blue light through completely.
How should I change glasses?
On the YouTube Propeaq channel there is a video explaining the box contents and how to change the glasses. No force is needed to push the glasses out of the glasses. Press lightly on the outside of the glass, inwards. The glass hooks on the nose bridge with a recess in the frame. New glasses are first placed with the recess in the nose bridge and then the glass clicks into the frame.
I’m already wearing glasses. Are there prescription lenses?
The Propeaq glasses only need to be worn with light switch on, for half an hour. If you cannot see enough because yo normally wear glasses, then you can find opticians on the propeaq.com website who can provide the glasses with prescription lenses. These glasses are also interchangeable. If one only needs reading glasses, the glasses can be combined with a Nooz reading glasses.
How long can the glasses be used without charging?
A full battery is good for 2 to 3 hours of active light. Since 30 minutes a day is often sufficient, you can use the glasses for 4 to 5 days. By pressing the on / off button, the 3 LEDs indicate the remaining battery charge. It is advisable to charge the glasses with 1 LED.
How long must the glasses be charged?
Two hours on the included USB charger is sufficient to fully charge the battery. Connecting longer to the charger is no problem, but we do not recommend this.
How do I charge the glasses?
Of course we recommend using the supplied USB charger and cable. However, the glasses can be charged on any standard USB charger with an approved USB cable. On laptops it usually takes a little longer to charge the glasses.
If a part is lost, how do I get a replacement?
Propeaq glasses have a warranty period of 1 year from the date of delivery and covers the products on material and production errors. Glasses can always be ordered separately.
Has scientific research been conducted into the operation?
A great deal of research has been done into the effect of blue light. The Propeaq glasses are even used in a number of studies as a reference because these glasses are the only ones that produce exactly the wavelength of blue light where the scientific studies have noted positive effects. There are links to the various studies on the propeaq website. The researchers Hall, Rosbash and Young have won a Nobel prize for medicine for their research into the biological clock in 2017.
Can the glasses be customized?
The frame is designed to fit most people. The Propeaq glasses are therefore available in 1 size. Like the better frames, the legs are slightly adjustable by an optician. The glasses are less suitable for children or broad heads.
Are the glasses available in more colors?
The Propeaq glasses are supplied in one combination of glossy / matte black frame with anthracite legs.
