I so appreciate the work that the Allay Lamp team is doing, as a chronic migraine sufferer myself. So far, I have found the Allay Lamp very easy to use and easier on my super sensitive eyes than normal light sources. I have been using it most days of the week and have recommended it to my friends who also have chronic migraine. It is comforting during periods of high pain. I have even fallen asleep with it on numerous times. The Allay Lamp is incredibly light and portable. I take it with me on overnight trips. I have been impressed with how long the charge lasts. I even use the reading shade, so I can read or write with a light source that doesn’t directly hurt my eyes.
