Glare is a scattered reflection of source light.
Hi Dave,
This is a definition by example, and as such is a weak one because it
can be shown that other example definitions neutralize it.
Glare is first and foremost a subjective interpretation. In other
words it has to be observed by a human and described as distinct from
other sources of light. As such, the common vernacular easily allows
the expression of "the glare of the noon day sun" when in fact there
are no reflections being observed. Stage lights are said "to glare,"
again without any notion of a specular surface. In fact, the
vernacular allows that a steady stare with malice is a "glare."
The point of the matter is that to say something is anti-glare; and
for the specific notion of what glare means having to be ferreted out;
then this necessarily throws the original statement into doubt and
confusion (which makes it perfectly suitable for internet posting :-)
It is absurd to call an application anti-glare without commenting on
the wavelength of the source, as you point out. To this point it
appears that it only works for red (and no other color). This is, of
course, true, and simultaneously irrelevant to common applications.
