For frequent international flyers jet lag can be a serious problem, interfering with one's daily routine and preventing one from sleeping; however one company aims to solve all that with a pair of clever light-emitting glasses, while a recently launched website offers tailored suggestions for re-setting one's body clock with natural light.

The Re-Timer glasses were showcased at this year's consumer tech extravaganza CES which ran from January 11-14. Though they have been available in Australia for the past few months, their appearance at CES marked the launch of the glasses in the US market.

The glasses were developed based on 25 years of research from Flinders University and emit a particular type of green light. In a statement on the Re-Timer website from Professor Leon Lack of Flinders University explains that this green light allows users to "transition their body clock to a new time zone in small steps. This eliminates the sudden change people experience after flying and reduces the symptoms of jet lag".

Following the instructions provided, users then wear the glasses for a certain period depending upon their set-off point and destination, for example on the website it suggests that a user flying from Sydney to Berlin would wear the glasses at specific different times in the day for 50 minutes before catching the flight, then again at another specific time for 50 minutes after arriving in Berlin.

The company suggests that the glasses, which retail for around $289, can also be used for overcoming sleeplessness, winter blues and as an aid for shift-workers.

Earlier this January a new free website called "Jet Lag Rooster" was launched to also help frequent flyers overcome the stresses and strains of jet lag by giving them a personalized "jet lag plan". Those wishing to avoid jet lag simply log on to, enter their departure point, destination, take off and landing times as well as the hours they normally sleep and when they wish to begin changing their sleeping patterns. With this information the website creates a personalized plan advising them when to "seek" or "avoid" light.
