Screen fatigue, dry eye and children's vision will dominate this year's National Eye Week which starts on Monday.
The annual spotlight on the nation's eye health organised and run by the Eyecare Trust is this year being sponsored by Optrex. In a major survey likely to receive wide media coverage, the Eyecare Trust will claim that some people of working age spend the equivalent of three and half months a year looking at a screen.
Britain's average couch potato spends 30.5 hours a week watching TV and the typical office worker spends 35 hours a week looking at a computer screen, the survey claims.
Despite suffering from symptoms such as eye strain and headaches at least one in 10 of the working population has never visited an optometrist, the survey found.
