Association between Exposure to Smartphones and Ocular Health in Adolescents

Authored By:

This is a cross-sectional study that looked into the effects of mobile phone use on symptoms related to eye health. A total of 715 adolescents participated in the study. Information on smartphone use and self-reported ocular symptoms (such as blurring, redness, inflammation, dryness, etc) was gathered via a questionnaire. The authors did not assess the exposure to RF from the smartphones. “Excessive” users of smartphones (defined as more than 2 hours/day) were found to be more likely to report multiple ocular symptoms. Users with a lifetime usage of more than 12 hours had a 3.05-fold higher likelihood (95% confidence interval = 1.51 – 6.19) of reporting multiple ocular symptoms compared to those with less than 3 hours lifetime use. The authors concluded that increasing use of smartphones can affect eye health.
