Jet Lag Solved

Jet lag is inevitable for most of us after long-haul flights. Or at least, it was. Australian researchers claim to have developed sunglasses capable of retuning your body clock. The "Re-Timer"-- as it's known-- isn't anywhere near as stylish as your favourite pair of Oakley or Ray-Ban sunglasses. In fact, it doesn't even come with lenses. But the device may signal the way forward in solving this very modern problem.

Developed by boffins at Flinders University in Adelaide, the "Re-Timer" uses green light to target the part of the brain responsible for controlling sleep patterns. Photoreceptors then register the presence of the light and awaken the body. Green light in particular is one of the most effective for influencing a person's body clock.

Professor Leon Lack, who spearheaded the project, told The Telegraph: "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 jet lag."

The "Re-Timer" comes with a built-in rechargeable battery, and can be charged up via a USB port. They can be worn while reading or using your laptop too. With this new eyewear-based invention, your designer sunglasses may not be hiding tired eyes on arrival again...
