Dark glasses aim to combat effects of jet-lag

IT may not be quite Jordi's visor from Star Trek, but glowing glasses claiming to combat jet lag have been developed by scientists in Australia.

The hi-tech glasses use blue and green light to fool the body clock. “Bright light is the tool which retimes our body clocks”, according to Dr Leon Lack from Flinders University in Adelaide.

A team of researchers there has designed 5mm wide light-emitting diodes, which reset travellers’ confused body clocks. The diodes are fitted on to the frame of ordinary glasses, and are powered by a 9 volt battery carried in a pocket.
