Sleep psychologist Leon Lack says the Re-Timer, eyewear that emits a light that stimulates the part of the brain responsible for our circadian rhythm, can help combat sleep disorders, according to EuroNews.

“It just occurred to us that light-emitting diodes, that are very small devices, very efficiently convert electricity into light and if they were mounted closer to the eyes, they would get enough light into the eyes and serve the purpose of the light therapy device. So basically, it brought the light source closer to the eyes and diminished the size of the light source,” says Professor Leon Lack, co-developer of the Re-Timer.
