Unbiased summary of the literature about myopia, some ideas about linkages between the various published results, and recommendations for shortsighted people and people who don't want to become shortsighted at all.

This book explains the issues involved in finding the proper prescription for your visual needs, and how you can realistically take matters into your own hands.

In this book, the author shares both the science and the “secret” of how he was able to reverse his own myopia: progressive retinal defocus technique.

Reprint of the original, first published in 1873.
