Purpose: This study was to measure and asses for confirming whether the use of smart phone was related to dry eye or not under various temperature and humidity.
Methods: Undergraduate applicants 30 subjects were studied under constant temperature and constant humidity for 2hr. who were divided into two groups: smart phone user group and non-user group. They were checked at 9 times in a person, whether they have dry eye or not, by using 4 kinds of dry eye examination which were questionnaire, Non invasive break up time, tear film Break-Up Time and Schirmer test.
Results: In McMonnies dry eye symptom questionnaire, we analyzed that low humidity and smart phone user group had 1.27 times (95% CI : 1.201-1.348) and 0.43 times (95% CI : 0.211-0.886) higher risk of dry eye than non-user group. And, in Schirmer test, low humidity and smart phone user group had 1.36 times(95% CI : 1.264-1.478) and 0.19 times (95% CI : 0.080-0.465) higher risk of dry eye than non-user group, which showed significant result. In tear film Break-Up Time examination, low humidity and smart phone user group had 1.23 times(95% CI : 1.176-1.303) and 0.15 times(95% CI : CI : 0.075-0.330) higher risk of dry eye than high humidity and non-user group. In non-invasive break up time examination, also it was investigated that low humidity and smart phone user group had 1.20 times(95% CI : 1.149-1.258) and 0.27 times(95% CI : 0.141-0.528) higher risk of dry eye.
Conclusions: We knew that low humidity and smart phone users were related in dry eye, but temperature was not related in dry eye.
