..Yes, a good point, however if it can be shown that even "a few" do,
then, for those, this could be valuable...particularly when this possible
"cause" is quick, simple, and inexpensive to check.

..So many are being diagnosed as ADHD ADD that I mean to suggest that
some may simply have a fairly easily detected vision problem that relates.

..Yes.  What to do about it?  Do the screening?  Give the medicine?

..Yes.  Maybe it is 1:1,000 or 1:10,000.  I think we generally agree
here.  I am suggesting that this at least be considered for all 10,000.
 There are a lot of people out there who are suffering with this
overall diagnosis.  If there are only a few who can be simply shown to
have constricted vision fields that are related to their problem, it
seems worth it to consider.  There is no clear research to back this
up. That's why I think it is needed.
