Coloured overlays for pdf reader?
So,
I have an issye where reading black writing on a white background gives me massive headache, and tends to cause more visual disturbances on the page (i.e. shadows of words floating around on the page is not fun). As a student who has to read a lot of journal articles this is....less than ideal.
My question is this: does the PDF reader have any ways i can add a coloured overlay over existing PDF's to make reading them easier?
