The iPhone has changed us in a fundamental way. Smartphones have been described as the culprit responsible for wrecking attention spans, disturbing sleep patterns and affecting eyesights. As part of our week-long coverage of the 10th anniversary of the iPhone, we consult with three experts to help us disentangle fact from fiction when it comes to how the iPhone has affected our brain, our sleep and our eyesight.WIRED talks to University of Oxford sleep researcher who has co-authored the book Sleep, a very short introduction. According to Russell Foster, The problem with smartphones is that they represent an additional delay to sleep onset. Now the group most vulnerable to this are teenagers, of course.

It is sort of a compulsion, almost an addiction. And that seems to be delaying further sleep onset. It’s a sort of biological predisposition that has been enormously exaggerated. On a school night many kids are getting less than six hours every night and it's been estimated that for full cognitive performance in teenagers at that age you need about nine hours of sleep. What happens with delayed sleep onset is that their performance in schools in the morning is particularly bad. They're chronically tired. Hotmail Customer Service
