Leave your sleeping pills behind as Re-timer, a possible cure for jetlag has been released commercially. The new portable device claims to reset the internal body clock, helping long-haul travelers get back on track.

Developed by Australia’s Flinders University after 25 years of sleep research, the Re-timer glasses have been commercially launched this month.

The new wearable device, available online for AU$249, (US $259) claims to reset the body’s internal clock by emitting soft green light into the user’s eyes.

After being exposed to the light, long-haul travelers as well as shift workers should find it easier to wake up in the morning and stay alert during the day.

The Re-timer uses LED (or Light-emitting diode) technology that mimics sunlight, stimulating the part of the brain responsible for regulating the body’s internal clock.

Before their trip, travelers are advised to calculate how long they should use the device per day and the number of days to use it with the design company’s jet lag calculator in order to adjust their body clocks.
