What is a jetsetter to pack? Loose travel wear, moisturizing cream… and some LED glasses? According to recent reports from Flinders Tech, the company is developing glasses for sale next year that could come in handy for anyone who suffers from frequent jet lag.

The Daylight Savers are glasses equipped with a pair of bright blue LED lights that shine directly into the eyes, delaying circadian rhythms.

Circadian rhythms are cycles of the body that control functions such as appetite, mood, and sleep. They are kept in sync with nature - more specifically, they respond to light. This means the body gears up at sunrise and prepares for rest at dusk.

While Flinders Tech is marketing the Daylight Savers towards people who rack up frequent flyer miles, affiliated scientists told the Philadelphia Examiner that there was no "single niche market." The glasses - which will contain a 9 volt replaceable battery - might be used to cure a variety of sleep disorders.

For years, scientists have been trying to harnessing light energy to use for the therapeutic treatment of circadian rhythm disorders and LED lights, with their unique brightness, are proving particularly promising.

Researchers for Renssalaer Polytechnic Institute in New York have been exploring how to use blue LED lights to keep night truck drivers awake. According to LightandKnives.com, the scientists hope LED lights could improve road safety and significantly reduce the 30 percent of fatal accidents involving large trucks in the America.
