الوصف: | Purpose: This study investigates the change in ocular function among young schoolchildren following nearwork with and without visual display units (VDU). Methods: Thirty-one young schoolchildren played computer game (VDU work) and paper game (non-VDU work) continuously for 2 h at 40 cm. Non-invasive tear break up time (NIBUT), blinking rate (BR) and palpebral aperture size (AS) were measured before and after VDU work and non-VDU work. Reading for NIBUT, BR and AS were normalized by converting into log10 unit. Results: MANCOVA analysis shows that logNIBUT is significantly reduced after both nearwork (F1,49 = 58.10, p 0.01). Pairwise comparison shows that modes of nearwork produce significant different effect in post-task log BR (F1,53 = 7.13, p = 0.01) and log AS (F1,53 = 11.00, p |
