Now, glasses that prevent jet lag and insomnia

The battery-powered glasses, which are on sale in the UK on the website for 162 pounds, can be worn while completing normal daily tasks such as working on the computer or reading.

Almost 94 per cent of passengers experience jet lag after a long flight, the report said.     

This is because travelling through different time zones confuses the body clock, which uses cues from the outside world – such as light, dark, silence and noise – to tell the body when it should be asleep or awake.
