Purpose: This study introduces a reading chart application for the iPad tablet in the Korean language and investigatesthe reading speed in a normal-sighted population according to age group. Methods: Sixty-three Korean sentences were selected from textbooks for second grade elementary schoolstudents. A commonly used typeface in everyday printed material, “BatangChe,” was used. Letter size waspresented in logarithm of the minimum angle of resolution (logMAR) 0.0 to 1.0 at 0.1 logMAR steps at a readingdistance of 40 cm. A third generation retina display iPad was used to present the chart, and the sentenceswere presented randomly for each size of letter. The subjects repeated the test silently (reading only) and outloud (reading and speaking) to prevent them from skipping reading words. Pilot testing followed in 65 normalvision adults under 60 years of age. Results: The mean reading only speed for logMAR 0.5 optotype (point 10) was 121.1 ± 47.2 words per minute(wpm) for people in their 20s (n = 21), 116.5 ± 38.3 in their 30s (n = 27), 93.8 ± 12.6 in their 40s (n = 9), and56.5 ± 42.7 (n = 8) in their 50s. There was a significant correlation between age and reading and speakingspeed (r = –0.48, p < 0.001). The mean reading only speed for logMAR 0.5 optotype (point 10) was 202.3 ±88.4 wpm and the mean reading and speaking speed was 129.7 ± 25.9 wpm, with significantly different (p <0.001). Conclusions: This Korean reading chart application could present a new standard when checking readingspeed according to age groups.
