In this essay the author contends that myopia is caused by the overflexion of the head on the trunk in the attempt to use the eyes for near work. He explains his theory on the ground of gravity pulling the eyeball away from the optic nerve, thereby lengthening the axis and causing short-sightedness. In consonance with his theory he proposes that schoolbenches be so constructed that unnecessary bending of. head and trunk be obviated. Further. pupils should be constantly admonished to maintain an upright posture while reading or writing.
