The Anomalous (or Induced) Myopias and the Intermediate Resting Point of Accommodation

Abstract

ABSTRACT Many theories have been suggested to explain independently the induced myopias — night myopia, empty field myopia, instrument myopia and small pupil myopia. Results of recent research have not supported these theories but instead have lead to the revival of a theory suggested as long ago as 1937.
