I originally bought it for a sunlight substitute when I can't handle getting out in the daytime for vitamin d like sunlight gives you but I was mistaken, it's not light therapy but it's very helpful for migraine sufferers when you are still too sensitive to be exposed to lighting you can normally tolerate. I get migraines several times a week and these are perfect for me just before one hits or when I have just been relieved of one but still recovering...
