I will have to try it again with perhaps a different way of thinking about it.
I'm really sorry it didn't work for you the same way, but I'm sure, you are right about the way of thinking - there is definitely a connection between the state of the mind and the eyes.
My 'weak point' , which causes strain and stress in my mind - as in my eyes - is, that I always fight against the 'blurr'; that is to get everything organized and under control, to fit in the pattern or frame of my life; it doesn't have to be all perfect but at least I have to be sure, that I can handle the situation. I find it difficult to let the situation just be as it is and not worry about problems, for which there is no solution possible at the moment and to concentrate only in what happens here and now (concentrate in a small point of life). It therefore helps (my vision and my state of mind) when I just try to remember the way I looked at the world as it is
when I was a child - not always comparing it at once with the world as it should be
in my eyes. When I remember how I child can get 'lost' completely in a momentary situation and try to find the same 'look', I can really feel a burden falling from mind and eyes and feel relaxation (and improved vision) at once.
Perhaps you should concentrate on finding out, which is your 'weak point', what stresses your mind and prevents you eyes to get full relaxation.
I hope you can find your way to avoid glaucoma. My mother is having that problem too (she is not short sighted); I showed her how to palm and she is doing it often (more often than I do) and finds that it helps her.
