When positioning your AYOlite on your head, the frame of the wearable should be on the level of your eyebrows so that the light will enter your eyes properly. If the frame is positioned above your eyebrows, the light will be blocked. And if the frame is positioned below your eyebrows, it will block your vision. Please refer to the picture below.
If you are wearing prescription glasses, please refer to this article.
! During a session, you should look straight, down or sideways but not directly to the light.
