Survey of Contrast Research

Arditi and Faye [2004] performed the latest research on the decreasing
relationship between font size and the level of contrast. Rubin and Legge
(1989) demonstrated the need for a higher contrast threshold for people
with low vision (reduced visual acuity). The discussion of contrast in
Understanding SC. 1.4.3 is extremely good, except that the relationship is
not as linear as implied by the presentation. Still Ariditi and Faye
established that as size goes up the contrast threshold goes down. The
reference to font-size guidelines from the American Printing House for the
Blind were developed in a context of print material.  It is less relevant
in an era of digital documents. Arditi,

Note: Do we need more surveys?
