What a diversity of challenges humankind has had to face during its
evolution, most of which it has also managed quite well. There is one
challenge above all others, however, in which humankind has so far
failed spectacularly, and if it does not take the message of this book
seriously, it will also perish with the demands of accurate close work.
For a time we will manage somehow, but without relieving accommodation
strain, the requirements of accurate vision in our modern society will
destroy the humankind's ability to see. The means to which ophthalmology
has resorted so far do not lead to the desired outcome. If we keep
following that road, before long the demands of doing close work, which
have increased at a tremendous pace, will destroy the eyes' ability to
see. Only by taking seriously the instructions for relieving
accommodation strain explained in this book can we save the sight of
humankind.
