There appears to be no difference in vision syndrome amongst students using digital versus printed textbooks even after adjusting for relevant covariates, according to a study.
The observational study assessed 231 Spanish students (15-17 years old) using either printed textbooks or digital textbooks at 4 time points.
Computer vision syndrome prevalence was 56.7% and 58.7% among printed textbook and digital textbook users, respectively. A higher likelihood of computer vision syndrome was associated with being female and having an uncorrected refractive error.
