Objective To examine whether explanatory illustrations can improve older adults’ comprehension of written health information. Methods Six short health-related texts were selected from websites and pamphlets. Young and older adults were randomly assigned to read health-related texts alone or texts accompanied by explanatory illustrations. Eye movements were recorded while reading. Word recognition, text comprehension, and comprehension of the illustrations were assessed after reading. Results Older adults performed as well as or better than young adults on the word recognition and text comprehension measures. However, older adults performed less well than young adults on the illustration comprehension measures. Analysis of readers’ eye movements showed that older adults spent more time reading illustration-related phrases and fixating on the illustrations than did young adults, yet had poorer comprehension of the illustrations. Conclusion Older adults might not benefit from text illustrations because illustrations can be difficult to integrate with the text.

Neither young nor older adults appear to benefit from explanatory illustrations accompanying health-related texts. However, older adults appear to have difficulty understanding the illustrations as well as integrating the illustrations with the text. These difficulties not only increased total reading times but also affected fixation patterns, and responses to the comprehension tests.
