An invention has been showcased at the Consumer Electronics Show in Las Vegas, which may help those who regularly cross the oceans. The Re-Timer is said to be able to help fight jet lag.

Claire Hoban explained how by blasting LED lights into our eyes we can be made to feel "more alert".

On the product's website, users of the device can enter travel details into a jet lag calculator to work out when to wear the headband in order to try and avoid feeling tired after travelling across time zones.
