Purpose: This study aimed to compare eye fatigue, forward head posture, and neck and shoulder discomfort according to vision correction status (corrected visual acuity 0.7 vs. 1.0) among college students who participated in online learning during the coronavirus disease 2019 pandemic. Methods: Twenty students from Chungnam B University, with pre-vision correction of 0.7 or less and full vision correction of 1.0, were enrolled. For subjective eye fatigue, the Virtual Reality Symptom Questionnaire was used, and the angle of the forward head posture was measured using Image J software after taking pictures in the sagittal plane. A visual analogue scale was used to measure the discomfort at the neck and shoulders. Results: Overall eye fatigue, forward head posture, and neck and shoulder discomfort were significantly increased in students with low-vision correction (0.7) compared to those with full-vision correction (1.0) (p<0.050). Conclusions: Based on these results, this study suggests that vision correction must be considered for the prevention and treatment of the forward head posture.
