For every 45 minutes in which you are focusing on something like a phone or a tablet or a book page or your computer, you want to get into Magnusellar panoramic vision for at least five minutes. And the way that I suggest to do this is actually to take a walk ideally outside. So for every 45 minutes or so, try and get five minutes of relaxing your eyes. Look off into the distance. Looking at a horizon will automatically trigger this panoramic gaze, which is very relaxing to the eyes and will allow you to go back into a focused work bout.
