Vision and Visual Dysfunction

Part 1 Introduction to the optics of vision: a functional approach to comparative vertebrate and invertebrate optics, Hughes; optics of the human eye, Charman. Part 2 Ocular ametropia and its correction: refractive error in relation to the development of the eye, Young; possible causes of abrupt changes in refraction; paraxial optics of ocular correction, Long; correction by spectacle lenses, Fowler; contact lens corrections, Efron; intra-ocular implants, Ridgway; surgical techniques for refractive correction, Halliday; binocular vision through correcting lenses, Jennings; optical aids for low vision, Dickinson. Part 3 Other aspects of visual optics: accommodation and its anomalies, Ciuffreda; retinal fibre optics, Enoch and Lakshminarayanan; polarised light and the eye, Bour; binocular vision in relation to stereoscopic instruments, Charman and Jennings; entoptic phenomena, Palmer. Part 4 Instrumentation for determining the optical parameters and refraction of the eye and of correcting lenses: non-optical techniques for visualising the eye; optical methods for measurement of ocular parameters, Henson; determination of ocular refraction, Howland; instrumentation for verification of spectacle and contact lens parameters, Loran.
