The concepts of spatial frequency and modulation are introduced. The Stiles-Crawford effect, entoptic phenomena, and glare are studied. The course ends with a discussion of ocular accommodation and its stimuli, which brings together much of the material on the optics of vision. The course provides a foundation for the techniques and procedures of clinical refraction, and a background for the diagnosis and treatment of vision anomalies. The course is organized into approximately 12 topical areas, each designed to expand on the previous sections, and build toward a comprehensive view of the optics of vision by the end of the course.
Clinical application is emphasised wherever possible.
Vision, Ambient Optic Array, Retinal Image. Reduced Eyes, Simplified Eyes, Schematic Eyes. Badal, Scheiner Principle, Laser Optometry. Vision, Ambient Optic Array, and the Retinal Image. The course is introduced with an overview of the visual process, and the way in which the environment structures the light before it reaches the eye.
