Script to do reverse video, or may be an access to the innards to turn the rendered stream reversed

Question

Hello Experts,
A whole bunch of us who have undergone what might be described as traumatic treatment have been handed over a bunch of pdf ebooks to read for rehabilitation and alternative employment.
But the eyes hurt a lot from the white glare of the monitor. In the good old days there were simple viewers that supported reverse video option.
How to write a script that can reverse the video of the acrobat as one can do in many other programs?
Is there also a way to make the image permanently inverted in pdfs ? There is some issue with grey and color image based pdfs or vector ones which use rendering into colors than simply black and white.

This feature to me is purely useless as there are many documents that are not
vector including the ones I mostly deal with in connection with research from
the peer reviewed journal of 911 studies or old journal scans. I need an adobe expert to provide
a solution to this basic problem or escalate it to a level to create a solution if
one does not exist, ie how to obtain a reverse video setting for the bitonal images
without actually reversing them. I bet there is a bit somewhere in the pdf standard
that can allow this toggle to be done.
