An eye expert has shed some light on how harmful staring at computer screens can be for eyes.
Speaking to the Guardian, Dr Rob Hogan, professional services director for opticians Dollond & Aitchison, said that in some people eyesight can deteriorate in a person"s late teens and early 20s.
This is called late-onset myopia and can be exacerbated by the increased use of computers.
He added: "The computer screen is at a very unusual distance visually. We read a book at arm"s length, which is about 40 cm from the eyes, or focus on things which are around 10 to 15 ft away, so working at a screen that is placed around 60 to 70 cm away is a new concept for our eyes to focus on over long periods."
A study recently carried out by the Kaiser Family Foundation revealed that children are spending an average of seven hours and 38 minutes a day consuming electronic media.
