** My two cents.

(1) Most everybody knows about poor acuity, sharpness of focus, and
that magnification is the usual fix, but many are not aware that it
also calls for word wrap to keep the copy on the screen when
magnified.
** SC 1.4.8 (Level AAA): Visual Presentation
[http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-visual-presentation.html].
Since this is a multi-part criterion (5 requirements in all), a fix
could address your concern in (3). 9th para under the intent refers to
word wrap, and I quote, “Wrapping should always be possible as long as
words are not so long that a single word is more than half the width
of a full screen. Very long URIs may run off the side of an enlarged
screen, but they would not be considered text for "reading" and,
therefore, would not violate this provision.”

(2) Fewer people know about poor contrast sensitivity, the ability to
distinguish between shades of gray or colors, and that the fixes are
heavier lines and bold fonts. Magnification helps to see the print,
but a larger skinny character is still skinny and hard to read. The
viewer needs choice of font.
** SC 1.3.1 (Level A): Info and Relationships
[http://www.w3.org/TR/UNDERSTANDING-WCAG20/content-structure-separation-programmatic.html],
based on the fact that it is hard to read due to a poor choice of
font. Refer to the technique ‘C22: Using CSS to control visual
presentation of text,’
http://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/C22

(3) Limited visual field is usually caused by retinal damage, but also
by poor acuity requiring a short eye to screen distance. The fix here
is minimizing the screen width and pulling in the margins to give a
narrow
column of copy. which in turn calls for word wrap to keep the copy in
the column. Many IT professionals are unaware of the limited field
problem.
** SC 1.4.8, (1) above and a possible technique ‘H87: Not interfering
with the user agent's reflow of text as the viewing window is
narrowed,’ http://www.w3.org/TR/2012/NOTE-WCAG20-TECHS-20120103/H87
may help.
