Impact of adherence to American Optometric Association guidelines on computer vision syndrome and dry eye

Abstract

Background: Prolonged digital device use among university students has been linked to computer vision syndrome (CVS) and dry eye disease (DED).

Aim: This study aimed to assess adherence to the American Optometric Association (AOA) guidelines and its impact on CVS and DED among male university students.

Setting: The study was conducted at Qassim University.

Methods: This cross-sectional study involved 290 male students. Data were collected through validated questionnaires assessing symptoms of CVS and DED, along with self-reported adherence to AOA ergonomic guidelines. A statistical analysis was used to correlate ergonomic practices.

Results: The study found high frequency of CVS (80.34%) and DED (68.28%) among participants. Eye irritation, headache, burning in the eye and tearing were the common reported symptoms of CVS, with a frequency of 43.35%, 41.20%, 36.10% and 35.62%, respectively. Significant reductions in CVS symptoms were noted among students who maintained at least 50 cm screen distance (P = 0.047) and those taking regular breaks (P = 0.000), highlighting the effectiveness of these ergonomic interventions. However, there was no significant reduction in DED symptoms among students who followed the recommended guidelines.

Conclusion: The high frequency of CVS and DED among students underscores the need for increased awareness and implementation of ergonomic practices. Thus, public health initiatives must enhance ergonomic education to improve student ocular health in digital environments.

Contribution: The study showed high frequency of CVS and DED among university students. Significant reductions in CVS symptoms were noted among students who maintained at least 50 cm of screen distance and those taking regular breaks.
