Great news for air travellers as new invention promises to put an end to time zone tiredness.

Air travellers: are you tired of being tired? There’ll be no more falling asleep at your desk or waking up starving at 3am thanks to an amazing new invention.

Along with long queues at the check-in and a lack of complimentary champagne on low-cost airlines, jetlag is one of the most common complaints about travelling by plane. However inventors could be set to call time on body clock issues with a new pair of futuristic glasses called 'Re-Timer' that they say will stop you getting jetlag.

The world’s first ‘time control’ glasses (pictured above) emit a special green light that has been scientifically proven to re-programme out-of-sync body clocks. The space-age specs, named ‘Re-Timer’, emit a soft green glow which stimulates the part of the brain responsible for regulating the 24-hour body clock. This sends signals to the rest of the body to create our daily cycles known as circadian rhythms, including our sleep patterns.

Inventor Professor Leon Lack, of Flinders University in Adelaide, South Australia explains: 'Using a light device allows you to transition your body clock to a new time zone in small steps. This eliminates the sudden change people experience after flying and reduces the symptoms of jetlag'.

If you want to go to sleep and wake up earlier than usual, you should wear the device for 50 minutes in the morning, while if you want to stay up and wake up later, you should wear them for 50 minutes before bed to delay the body clock, say researchers.

The Re-Timer glasses are on sale for just £162. They can be worn while completing normal daily tasks such as working on the computer and walking the dog. Watch the promotional product video:
