Purpose: The aim of this study was to evaluate the readability of a Hangul font with background colors of printed materials in the presbyopic age.

Methods: Fifty-seven subjects (average age, 65.75¡¾10.85 years; 23 men and 34 women) were enrolled. The Hangul font and background colors printed for evaluating readability were black letters with Sinmyungjo of 10 point (pt) and white, blue, green, and yellow. Near visual acuity (VA) was corrected to read VA 0.5 (6.3 pt) at 40 cm after distance correction. The subjects were asked to select a preferred color. Readability was assessed by reading rate as the number of words read correctly in one minute (words per minute, wpm).

Results: Readability was the highest on a white and the lowest on a green background. This tendency was shown to be similar to preferred colors. There were no significant differences for readabilities with background colors between genders, and cataract surgery and non-surgery. Differences for reading errors between background colors were also not significant. There was a weak positive relationship between readability and lightness difference, but no relationship was found between readability and color difference.

Conclusions: Black letters on a white background usually had a high readability. The differences of readabilities among background could be partially elucidated by lightness differences. However, various factors such as individual¡¯s visual function and environment may be needed to account for these differences in greater detail.
