HISTORICAL PERSPECTIVE
ON THE DEFINITION OF HYPERMETROPIA

By C. H. BROWN, M. D. 1921

Hypermetropia may then be defined as that condition of the eye in which there is a shortening of the antero-posterior diameter of the ball, or the positive refracting power of the eye is deficient, and the result in either case is that the focus is behind the retina.

Or, in other words, the diameter or length of the eye-ball is less than the focal length of its dioptric apparatus.
