This study surveyed the reading discomforts and the reasons for discomfortable reading of the safety and health information (texts and icons) presented on the agricultural vehicles/machines, pesticides, fertilizers, and feeds. Eighty seven people residing in rural area participated in the survey interview. Questionnaire survey showed that the most discomfortable product in reading the texts was pesticides. Forty three (49%) among participants had very-discomfortable or discomfortable in reading the texts used in the label of pesticides, and the main reason for the discomfort was small text size. The reading discomforts in reading the texts (varied from 4 point to 19 point and presented in 50 cm reading distance) showed different pattern according to the age groups. Three age groups (50s, 60s and older than 70s) showed a similar discomfort pattern, but different from the group of 30s and 40s. Forty four people (51%) had a problem in understanding the meaning of the icons and the main reasons were the small size and the difficulty in inferring the meaning of the icons. Thus, the more detailed and practical guidelines for the presentation format, particularly about the text heights and the size of icons, are required. Also, more comprehensive research is needed to investigate the readability and legibility of texts and icons.
