Astigmatism

More Americans than ever before are attempting to correct their vision without having to wear glasses or contact lenses. By working on Bates method exercises illustrated in this book at home for half an hour a day and applying some simple techniques in everyday life, most people have at least a 75 percent chance of achieving partial or complete success in restoring their vision. Almost half a million Americans underwent corrective vision surgery in 1999 (more than double the number who attempted it the year before), and complications that may arise from these procedures are still uncertain, as the science is so new and untested. The Bates method of eyesight improvement is nonsurgical, completely safe, and quite effective. This simple and practical guide to using the Bates method is completely up-to-date and addresses all the common faults of vision -- nearsightedness, farsightedness, astigmatism, and "old age" sight.

Astigmatism - In optics, astigmatism is a monochromatic aberration in which an optical system has different focal planes for rays in different planes. Lenses and mirrors which are partly cylindrical show this behaviour already for on-axis rays, parabolic mirrors and uncorrected lens systems only proportional to the squared angle between rays and optical axis.

Acuvue - ... made by Vistakon, a subsidiary of Johnson & Johnson, is among the world's most popular brands of disposable contact lenses. The line includes Acuvue, Acuvue 2, Acuvue 2 Colors, 1-Day Acuvue, Acuvue Bifocal, Acuvue Toric, Acuvue Advance, Acuvue Advance for Astigmatism, and Acuvue Oasys.

Bifocals - Bifocals are eyeglasses that have corrective lenses containing two different lens powers. They are most commonly prescribed for people with presbyopia, and who also require a distance correction for myopia, hyperopia, and astigmatism.

Corrective lens - A corrective lens is a lens worn on or before the eye, used to treat myopia, hypermetropia, astigmatism, and presbyopia. The most common types of corrective lenses are spectacle lenses and contact lenses.

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.
