Introduction The purpose of this study was to determine the association of screen media exposure and decreased visual acuity among public school students in Quezon City. The study focused on three level of exposure: duration and frequency of exposure and distance from screen media. Television, hand-held consoles and computers or laptops meanwhile were the screen media devices included in the study.

Methods This study was conducted among 10 to 11 year old students from two public elementary schools in Quezon City. The visual acuity was determined through self-reporting and assessed through a visual acuity examination. The duration and frequency of exposure and distance from screen media were determined by an interview-guided questionnaire among students with decreased visual acuity and normal visual acuity.

Results A total of 130 subjects consisting of 69 with decreased visual acuity and 61 with normal visual acuity. Those with decreased visual acuity were mostly females (62.3%). The odds of moderate to severe exposure among the cases was 3.98. The adjusted odds ratio, after considering the effect of family history and eye-straining activities, was 6.48. Frequency of exposure and distance to screen media did not show any significant association. 

Conclusion This study showed a significant association between decreased visual acuity and moderate to severe duration of exposure but not with frequency and distance from screen media.
