First Edition. Garrison-Morton 1487. The second of three major papers in physiological optics published by Young between 1791-1801. In his decade of research on vision, light and color, Young solved the major problems still left in eighteenth century theory, and introduced new problems for the nineteenth, earning for himself the epithet, "father of physiological optics."

The present paper has been called "the most important treatise on physiological optics published up to that time" (Hirschberg/Blodi V, 22). Young described his improvement on the optometer, analyzed the optics of the eye, made optometric measurements of its dimensions, and computed the changes in focal length for near and far vision. He made the first exact measurements of the visual field, and the first series of measurements on refraction and accommodative power. To show that changes of shape take place in the lens, he made use of his own astigmatism, giving the first clinical description of astigmatism.
