Hot on the heels of concerns of audiologists regarding iPod use, a warning about its video counterpart causing dry eye has emerged from the US.
About two million iPods have been sold in Britain, and the video version could catch on in the same way.
However, Dr Robin Vann, ophthalmologist at the Duke University Eye Centre in North Carolina, has already announced his concern to the state's news gathering service, NBC17.
He has seen patients who use other portable video devices, and expects video iPod users to complain of dry eyes.
'They're going to have redness. They're going to have headaches,' he said.
'I see people in their 30s and 20s who act and talk like they're 60- or 70-year-olds with their dry-eye problems.'
