Glasses that shine a light in your eyes — sounds like the world’s worst gag gift, right? But it may be just what the doctor ordered for frequent flyers. Designed to reprogram your circadian rhythms, these nifty — albeit bulky — sleep glasses needn’t even be carried on. Use them beforehand to program yourself for your destination on arrival.
