These glasses cannot be identified in any reviews. I was badly injured in Vietnam in 1972 and have had headaches ever since. I actually have headaches 24 hours a day, 7 days a week with a baseline pain level of 3. I wear headache goggles called Theraspecs, which I have to wear whenever I'm awake. They worked very well, but they are much more expensive. I found these glasses through a friend who has them and told me they can work. After buying these and wearing them every waking hour, I've found that they work just as well as others, maybe even better. They are also much more practical than Theraspecs. Day and night they are the best I've ever had. Daryl, ex-USN, DAV NAMWET.
