"Most patients are benefited merely by closing the eyes; and by alternately resting them for a few minutes or longer in this way and then opening them and looking at the Snellen test card for a second or less, flashes of improved vision are, as a rule, very quickly obtained. Some temporarily obtain almost normal vision by this means; and in rare cases a complete cure has been effected, sometimes in less than an hour.
But since some light comes through the closed eyelids, a still greater degree of relaxation can be obtained, in all but a few exceptional cases, by excluding it. This is done by covering the closed eyes with the palms of the hands (the fingers being crossed upon the forehead) in such a way as to avoid pressure on the eyeballs. So efficacious is this practice, which I have called "palming," as a means of relieving strain, that we all instinctively resort to it at times, and from it most patients are able to get a considerable degree of relaxation."
