Eye Astigmatism

This applications-oriented book covers a variety of interrelated topics under the study of optics. For physics and engineering, it covers lasers and fiber optics, emphasizing applications to the optics of vision. For optometry, it discusses the optics of the eye, geometrical optics, interference, diffraction, and polarization. Emphasizing the optics of vision, the book presents a vital and interesting applications of optical principles. It also includes several specialized sections on vision: a history of vision and spectacles; the use of vergences to handle refraction of the eye; the use of vergence to handle errors in refraction of the eye; optics of cyndrical lenses and application to astigmatism; aberrations in vision; structures and optical models of the eye; and the use of lasers in therapy for ocular defects. A valuable reference on optics for professional optometrists, physicists, and engineers.

Between 1919 and 1930, Dr. William Bates wrote about his breakthroughs in vision improvement in his magazine Better Eyesight. This book reprints all 132 issues of this influential journal, which offered nonmedical solutions to such problems as near- and farsightedness, astigmatism, crossed eyes, and lazy eye. It includes appendices on how to become a Natural Eyesight Improvement Teacher, a biography of Bates, and excerpts from his nurse/wife's book Stories from the Clinic.

An Eye for an Eye: The Untold Story of Jewish Revenge Against Germans in 1945 - An Eye for an Eye: The Untold Story of Jewish Revenge Against Germans in 1945 is a book by John Sack, claiming that some of the Jews who survived the death camps of the Holocaust took revenge on their former captors while overseeing over 1,000 concentration camps in Poland for German civilians and torturing them. Sack estimates that 60,000 to 80,000 people died.
