Basic Clinical Optics by Gilbert O Enechi
Requirements: .MOBI reader, 10 MB
Overview: Chapter one begins with the introduction of fundamental theories of light and vision, traversing through the primeval thinking to the current understanding, and acknowledging the early scientists without whose efforts this body of knowledge would have amounted to nothing. It introduces the reader to the concepts of wavefront, optical ray and the fundamental wave properties of light such as reflection, refraction, diffraction, polarization and interference. It further demonstrates how the properties of light are observed in nature as colours of sky and seas; moonlight; eclipse, day and night. The chapter prepares the reader and sets the stage for detailed discussion of properties of light as applied in clinical settings in the subsequent chapters.
Chapter Two discusses reflection as one of the fundamental properties of light. Using mirror as a model, it demonstrates how images are formed through reflection. It explains the laws and rules of reflection, mirror formula and finally, it considers the issue of total internal reflection as applied in keratometry where a refractive medium can also exhibit reflective properties. At the end of this chapter, the reader will be able to trace and draw ray diagrams of images formed by mirrors.
