Hermetic View of Eyesight Loss

["Dan" <hornedfox@...>]

Rawn,

Is there any Hermetic explanation as to why astigmatism and other 
forms of eyesight loss occur? I ask because I have been recently 
reading much about W.H. Bates, who said that by relaxing the eyes 
completely, normal vision can be restored over time 
http://www.iblindness.org/books/bates/. His techniques seem very 
similar to Bardon's in that he instructs his patients to use 
concentration and imagination to improve their eyesight, while 
eschewing paraphernalia. I'm curious to hear what you and other 
members of the group think...
