Sponsor's own description

This study aimed to evaluate the effect of anti-reflection (AR) and circularly polarized (CP) film on video display terminal (VDT) induced dry eye and asthenopia after limited time and close distance of visual tasks under light and dark environment, searching for new strategy for eye-protective electronic screen. The study was randomized, double-blind and controlled. Subjects were enrolled following the criteria: diopter of both eyes not exceeding -6.0D and anisometropia not exceeding 2.0D. and randomly divided into control, AR, AR+CP group in light or dark environment. Character searching, gaming and video tasks utilizing specific smartphones for totally 45 minutes were performed. Researchers measured the indexes of dry eye and asthenopia before and after tasks to evaluate impacts induced by VDT.
