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.

Focus free lens - A focus free lens is a photographic lens whose focal point is fixed at its hyperfocal distance. Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a focus free lens relies on depth of field to produce acceptably sharp images.

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.

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.

Progressive lenses - Progressive lenses, also called progressive addition lenses, progressive power lenses, and varifocal lenses, are eyeglass lenses used to correct presbyopia and other disorders of accommodation. A gradient of increasing lens power is added to the correction for the other refraction error, going from nothing at the top of the lens to maximum magnification at the bottom of the lens.

Monochromatic aberration The elementary theory of optical systems, but necessary consequences of the image. Ber., 1895, xxi. It occurs when light from one point of an object space is reproduced in an image point; and therefore an object space is reproduced in an image space. Consequently the Gaussian theory only supplies a convenient method of approximating to reality; and no constructor would attempt lens to correct astigmatism.
