To develop a reading chart app for the iPad tablet computer in the Korean language and to investigate reading speed in a normal-sighted population according to age groups.<br /> <br />
Sixty-three Korean sentences were selected from textbooks for second grade students in elementary school. Commonly used typeface in everyday printed material, “Batangche” was used. Letter size was presented logMAR 0.0 to 1.0 at 0.1 logMAR steps at a reading distance 40 cm. A 3rd generation retina display iPad was used to present the chart and the sentences were presented randomly for each vision and reading speed was checked twice. Pilot testing followed in 55 normal vision adults under 60 years old of age. The subjects read aloud to prevent them from skipping reading words
The average word count for the sentences was 6.5 0.7. The mean reading speed for logMAR 0.5 optotype (point 10) was 133.9 ± 26.1 words per minute (wpm) in 20s (n = 19), 121.1 ± 31.6 in 30s (n = 25), 96.8 ± 17.2 in 40s (n = 6), 67.7 ± 41.9 (n = 5) in 50s. The mean reading speed for logMAR 0.0 optotype (point 3.5) was 121.2 ± 27.2 wpm in 20s, 106.6 ± 34.9 in 30s, 61.4 ± 20.1 in 40s, 43.6 ± 77.2 in 50s.<br /> <br />
This Korean reading chart app can present a new standard when checking reading speed according to age groups. The app also provides portability and accessibility for this new reading acuity chart.
