Product Description
Review
"[A] splendid text... An extensive literature is embraced, as shown by the series of references for each chapter. Optometrists, with the care of pre registration students, and local groups in need of some gently controversial subjects, would do well to use this book as the basis for helpful discussions." "Professor Robert Fletcher", Optometry Today, November 1998
book, which reviews the field of myopia related to nearwork, is a good survey of the field."Acta Ophthalmologica Scandinavica

Product Description
Myopia is the technical term for short sightedness. It means that images of distant objects are focused in front of the retina when accommodation is relaxed and thus distance vision is blurred. Many texts describe the measurement of refractive error in myopia and how to correct it by conventional means, but very few discuss the condition in detail. Our book will discuss: prevalence myopia and near visual activity structure of myopic eyes animal studies accommodation and myopia innervation vergence and myopia treatment - behavioural approaches, control, spectacles, contact lenses, including OrthoK, laser surgery.

Worth It's Weight in Gold !!!, 11 Jan 2001
By Jim Amar - Published on Amazon.com
This review is from: Myopia and Nearwork (Paperback)
An excellent book detailing myopia research by contributions from some of the professional 'heavy-weights' in the field of Ophthalmology. The whole notion that one may 'learn' to improve their eyesight (myopia) has often fueled ridicule against such propositions and having decreased my own myopia from -4.0 diopters down to -2.0 (and still improving) by employing techniques mentioned in other related books on the subject of natural vision improvement, I was thrilled to come across such items as:
"Finally, Medina and Fariza (1987,1993) argued that the traditional correction of myopia with negative lenses reintroduces the error that initially simulated it's development, and therefore is likely to accelerate its progression. This conclusion is also compatible with the notion that individual eyes have preferred refractive set-points to which they return after being corrected ... " sec 3.2.1 page 35.
"The rapid development in electronic technology has, in recent years, extended greatly the facility to monitor biological activity and has stimulated and renewed interest in whether the extent to which we can exercise control over nominally involuntary autonomic functions has clinical utility in the treatment of certain psychological and medical disorders. Operant conditioning (or biofeedback) has, however, yet to gain general acceptance in the medical fraternity even though recent work has striven to resolve the methodological limitations of early investigations. Ophthalmic applications of biofeedback have achieved varying levels of success with regard to the correction of occulomotor anomalies .... "The principal aim is to train patients to gain greater control over voluntary accommodation in order to ameloriate functional myopia, although it is claimed that the facility can also be used to treat early presbyopia and latent hyperopia. .... "It is suggested that patients can anticipate improvement of unaided visual acuity to 6/9 or 6/6 with a commensurate reduction in myopia of 2 D to 3 D (Diopters). Of relevance to this chapter is that Trachtman (1987) also speculates that up to 2 D of myopia reduction occurs in the initial stage of training from a relaxation of parasympathetic-induced spasm of accommodation and that subsequent myopia reduction emanates from patient control of sympathetic-induced negative accommodation." Sec. 6.8.2, page 140. GO BUY IT NOW !!!!
