Abstract

This research explores typographic adjustments, specifically letter width, and their impact on patients with various visual conditions. These patients were divided into three groups of interest according to the visual condition they presented: blurry vision ( = 15), central vision loss ( = 11) and peripheral vision loss ( = 15). There was also a control group ( = 14). In an acuity experiment, six typeface variations were tested. Point sizes were used as a measurement of acuity. Results revealed that larger letter widths affected each one of the groups differently. These findings align with recent literature, which highlights that the effect typographic variables exert on readers varies depending on their visual condition.
