Myopic eyes are long, so why fool around.
A search of the literature indicated that apparently no one had ever suggested this, let alone made the attempt. I quickly rejected any mechanical means, such as some sort of calipers to compress the eyeball longitudinally. The obvious answer was centrifugal force, applied so as to push the eyeball from the front. The subject would sit in a chair mounted on a revolving base, facing inward toward the center of rotation. As the speed is increases, so does the centrifugal force exerted on the eyeball.
