Myopia Manual - 2022 Edition
Klaus Schmid
老式医学声称，近视是罕见的并且完全由基因决定，你能做的就是戴眼镜。预防近视或防止近视发展（或由此导致的失明）是不可能的。
然而，今天，很多人在父母和祖父母视力正常的情况下变得近视。另一方面，今天的生活与过去的生活有很大的不同——且不提工作环境和营养之外的变化。
找到造成近视的原因并一劳永逸地解决这个问题听起来太美好了！相当多的作者给人的印象是他们非常接近这个目标了，而大多数其他理论和观察的倡导者都是错的。
然而，更有可能的是，他们所有人在他们的实验和经验的具体观点上都是正确的，因为显然存在各种不同的和重叠的造成近视的原因同时存在。
秉持这种观点，本书以非常客观、中立的态度概述了研究人员和从业人员报告的预防和治疗近视的主要成果（使其成为简短的近视百科全书），并且仅在单独的一章中试图为这些结果找到一些共同的模式。
此外，还包括与近视相关的各种实用提示，以及一些总体建议。
Old-fashioned medicine was stating, that myopia is rare and exclusively inherited, and to prescribe glasses is all what you can do, and that the prevention of myopia or the prevention of the progression of myopia (or of a resulting blindness) is not possible.
Today, however, very many people are becoming myopic without myopic parents or grandparents. On the other hand, the life of today is very much different from the life in the past - just to mention the changed environment at work and the changed nutrition.
The idea, to find just one mechanism for myopia and to solve this problem once and forever sounds very tempting, and quite some authors are giving the impression that they are very close to this target, and that most of the promoters of other theories and observations are wrong.
It is by far more likely, however, that all of them are right in the very specific view of their experiments and experiences, because various different - and overlapping - mechanisms towards myopia are obviously existing.
According to this view the main results which were reported by researchers and practitioners for prevention and treatment of myopia are outlined in this paper in a very unbiased and neutral way (making it a short encyclopedia of myopia), and only in a separate chapter it is tried to find some common patterns for these results.
Additionally, some practical hints about various subjects, which are related to myopia are included, as well as resulting overall recommendations.
