Re-Timer glasses function as a wearable green light device to reset the body’s internal clock by emitting a soft light onto the eyes. Invented by sleep psychologists at Flinders University in Australia and developed through 25 years of research, they help reduce jet lag, increase energy during long winter months, overcome sleeplessness, and manage fatigue if you’re a shift worker.
The glasses have an ergonomic and lightweight design, with a rechargeable battery in the frame and a USB cable for charging. Their chief inventor, Professor Leon Lack, said the light stimulates the part of the brain responsible for regulating the 24-hour body clock:
Body clocks or circadian rhythms influence the timing of all our sleeping and waking patterns, alertness, performance levels and metabolism. Photoreceptors in our eyes detect sunlight, signal our brain to be awake and alert, and set our rhythms accordingly. These rhythms vary regularly over a 24-hour cycle. However, this process is often impaired by staying indoors, traveling to other times zones, working irregular hours, or a lack of sunlight during winter months.
He recommends wearing the glasses for 50 minutes every day for three days either in the morning to advance the body clock, or at night to delay it. Gizmag notes that the Re-Timer costs $258 from the website, which also offers a frequent flyer calculator that works out when to use the device to counter jet lag from your flight.
