The Eye, Volume 4: Visual Optics and the Optical Space Sense provides a well-integrated and authoritative account of the physiology of the eye. The book is organized into two parts. Part I on visual optics begins with a discussion of the branches of optics and the basic principles of geometrical optics. This is followed by separate chapters on refraction at plane and spherical surfaces; the thin spherical lens in air; reflexion at plane and spherical surfaces; the astigmatic lens; aberrations of optical images; ametropia and its correction; and retinoscopy and ophthalmoscopy. Part II on the optical space sense includes discusses of objective and subjective space; spatial localization according to direction; perception of distance and of size; spatial localization through binocular vision; special topics in binocular spatial localization; and ocular dominance and binocular retinal rivalry. Whilst the emphasis has been on readability rather than exhaustiveness, the various accounts are sufficiently well documented to make the treatise valuable not only to teachers in physiology, psychology and ophthalmology, but also to research workers in all branches of ocular physiology.
