“ It was found impossible to raise an army with even half normal vision in one eye, and in order to get the number of soldiers required it was necessary to accept for general service men whose vision could be brought up to half normal with glasses.2
Such figures as the foregoing, terrible as they are, by no means exhaust the subject. In fact they are only the beginning.
Errors of refraction are so common that we have learned to take them lightly. They are usually reckoned among minor physical defects, and the average lay person has no idea of their real character.

“ The condition known as conus in which the choroid, or middle coat of the eye, is destroyed in the neighborhood of the optic nerve exposing the white outer coat (sclera) and forming first a crescent and later even a complete circle is commonly regarded as one of the symptoms of myopia and attributed to the tension resulting from the lengthening of the globe, but Risley's statistics show that while it is somewhat more common in this state of refraction than in hypermetropia it is by no means peculiar to it. ”
