Quad43 Yes, it does completely eliminate the migraines I get from too much LED exposure. But, do know I still occasionally get headaches for other reasons. I'm beyond the eyestrain stage; now, even with the headache control, I cannot stand to be with screens that cause me discomfort. At this point my reaction is a learned on, as one learns not to touch a hot stove else be burnt. I hope, in time, I will be able to tolerate the offending lights, or find some glasses that help.
