The blue light that makes you happy!

A compact device, which can be taken anywhere, and plugs easily. The design very "welfare" is seductive with his touch silicone.
A leaflet that by cons makes you immediately forget the seductive design! "Wait in the eyes", it's time to say !!! So we no longer knows or ask on ... how far ... if it is enough on the side ... if it would not be better to put glasses!
In short, this little time spent psychosis, we finally decided to test the beast ... The use is simple: 2 buttons in front of it controls the on / off so that the timer, and the one on the side of the camera adjusts the intensity of light (3 possibilities).
First tip, look away hard-pressing the button "on", otherwise you will leave an eye, because the blue light comes immediately! And that's blue and bright! Second tip, if you have already lost an eye by not following the first tip, do not touch the brightness control, because the base is the lowest!

Out of there, the use of that light, within walking distance, is quite nice. I think that the assessment of its benefits on morale can be done over a period of time long enough. In any case, for having used regularly, it has had no negative effects (and I've prone to ophthalmic migraines).
Namely however, use is not recommended at night because it would induce a risk of insomnia. While understandable, this is a shame, because it reduces the use of this device slots for people working during the day. It remains the morning, but in my case, it is often the race, and the use of this dazzling light out of bed at the breakfast table, still falls torture!
By cons I find it very enjoyable holiday and we read a book. The clarity of the light makes me feel like the fingers of feet up in the lounger on my terrace.
