PURPOSE
Reading speed is one of the methods used to measure near visual function. Although several versions of reading charts in different languages have been introduced, there is no Korean version of the reading chart yet. Therefore, we investigated the reading speed of normal-sighted Korean people using a recently developed reading speed application for the iPad tablet in Korea. METHODS: Normal-sighted participants without presbyopia were included and a third generation retina display iPad was used to measure reading speed. The iPad screen was set to maximum brightness and the examination was performed at a distance of 40 cm. Reading speeds were recorded twice: one for reading the sentence silently (reading only) and one for reading the sentence out loud (reading & speaking). RESULTS: The test sentences used in the application had 18.9 ± 2.6 letters and 6.5 ± 0.7 words on average. Twenty-five males and seventeen females were included. The average of the reading only speed was 202.3 ± 88.4 words per minute (WPM), and that of the reading & speaking speed was 129.7 ± 25.9 WPM, showing a statistically significant difference (p < 0.001). CONCLUSIONS: This Korean reading chart application is the first self-reporting reading chart in Korean. This chart could present a new standard for measuring both reading only and reading & speaking speeds. |
