The book is for parents interested in treating their children who became nearsighted and for eye care specialists who may be interested in treating younger myopic clients. It will also appeal to adults who became nearsighted during development but decided to treat it during post-development. The book is also interest to anyone who became nearsighted during post-development and decided to treat it before it got worse. In these latter cases, the correctable range is lower due to the possible interference of other refractive errors at this stage.
