If you suffer from SAD (seasonal affective disorder) or from jet lag, you may have considered light therapy. Most light therapy devices I’ve seen are banks of lights that you must sit in front of for periods of time, and you may feel you don’t have the time to devote to this therapy. The Re-Timer glasses from Re-Time Inc say they will provide the light you need to keep your energy levels, sleep patterns, and body rhythms adjusted, but you won’t be tied to one location while you enjoy the therapy. The glasses are said to produce no UV. They’re portable and they even fit right over your glasses, so you can continue about your life while receiving the therapy. They are available in Australia and the US from the Re-Timer website for $273.90.
