Summary

Video display terminals (VDTs) are ubiquitous, and engagement in digital screens has grown substantially across all age groups worldwide. Prolonged exposure to VDTs is associated with the development of various health problems. By now, it is unclear whether transient exposure to VDTs leads to ocular surface changes, especially regarding lipid layer thickness (LLT). This study aim to determine if short-term exposure to light-emitting diodes (LEDs) leads to ocular parameter changes.

This is a prospective, cross-sectional study. Patients were recruited at the National Cheng-Kung University Hospital, a tertiary referral center in southern Taiwan, for examination, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), lipid layer thickness (LLT), and blink rates and patterns before and after watching an LED display for 15 minutes. The estimated result is that the LLT and blink rates will decrease after VDT watching.
