86. Visual Fatigue While Reading on a Computer Screen at Different Contrast Levels: An Eye-Tracking Study
DescriptionPrevious research has shown that reading on digital screens for extended periods of time can cause symptoms of visual fatigue, but there has been limited research on the effect of text contrast on long-form digital reading. This study uses a combination of objective (eye-tracking) and subjective (questionnaire) measures of visual fatigue to quantify the effects of contrast level on visual fatigue when reading for extended periods of time. Participants read the beginning portion of two fiction novels for 20 minutes each, one at high contrast (gray-on-white, WCAG 2:1) and the other at low contrast (black-on-white, WCAG 21:1). Preliminary results from a counterbalanced subset of 12 participants indicate that participants read less pages and had more blinks per page when they viewed the high contrast condition first and the low contrast condition second, potentially indicating higher visual fatigue for that group of participants.
