Amber lenses are a genuine tool for shift workers. Wearing them on the commute home after a night shift blocks bright morning light, which helps your body stay in night mode so you can actually fall asleep during the day. That is a real, practical use, not a gimmick.
Pair the glasses with blackout curtains and consistent sleep timing for the best shot at daytime rest. But be clear: glasses are not a cure for shift work sleep disorder. If it is seriously disrupting your life, see a doctor. An amber Night lens is one piece of a bigger routine.
