Hugh Pickens writes writes: "It is estimated that up to 94 per cent of long-haul travelers suffer from jet lag because the body becomes confused to traveling through different time zones. Now Andrew Hough writes that jet lag could soon become a distant memory for weary travelers with the development of a set of hi-tech “sunglasses”, described as the world’s first “time control” spectacles, which can imitate sunlight patterns helping world travelers adapt to changing sleep patterns and time zones in “small steps”. Dubbed the “Re-Timer,” the device targets a part of the brain that regulates the human body-clock, by sending signals to the rest of the body that help it slowly realize it is in a different area of the world. "The light from Re-Timer stimulates the part of the brain responsible for regulating the 24-hour body clock,” says Professor Leon Lack, a researcher on sleep, circadian rhythms, bright light therapy, and treatments for insomnia and the device's chief inventor. “Using a light device allows you to transition your body clock to a new time zone in small steps. This eliminates the sudden change people experience after flying and reduces the symptoms of jet lag.”"
