Sites prepared by private hospitals or medical centres constituted group 1, individual sites of ophthalmologists constituted group 2, and sites providing general health information that did not belong to group 1 or group 2 constituted group 3. In total, health information presented in 85 websites was analysed. According to Atesman and Bezirci-Yılmaz, the mean readability values were 49.6 ± 7.5 and 12.9 ± 2.8, respectively. There was no statistically significant inter-group difference in terms of the average number of sentences, of words, of words with four or more syllables and of syllables (p = 0.579, p = 0.434, p = 0.236 and p = 0.336, respectively). The readability values of groups 1 and 3 were significantly different according to the Atesman and Bezirci-Yılmaz formulas (p = 0.025 and p = 0.023, respectively). In terms of content, groups 1 and 2 had relatively more comprehensive information.
