The characteristics of visual display terminal (VDT) and related eye symptoms were analyzed. Research of the effect of VDT on visual function, visual development and characteristics of ocular surface was presented. Currently research still stays in the initial stage. Intensive research of VDT related eye problem will provide effective prevention and treatment methods for clinic work.

Purpose: To assess the impact of prolonged and intense exposure to video display terminals (VDTs) on ocular surface homeostasis.
Methods: 30 subjects limited daily VDT usage to less than 3 hours for one week, then extended usage to more than 8 hours/day for the next three weeks. Ocular symptoms and signs were evaluated weekly using the Ocular Surface Disease Index (OSDI) questionnaire and clinical examinations.

Objective: This study aimed to evaluate whether lacrimal gland tissue stiffness can aid in diagnosing dry eye disease (DED) using shear wave elastography (SWE). We also aimed to assess the correlation between the subjective symptoms of ocular strain, SWE values, and other ocular examination findings (Schirmer's test and tear film breakup time [TBUT]) contributing to the diagnosis of DED.
Methods: This cross-sectional study recruited 300 participants who were engaged in video display terminal (VDT) work and had been diagnosed with DED by an ophthalmologist for more than one year, and 100 healthy participants without DED symptoms, from August 2020 to December 2021.

Article Synopsis
- A study was conducted to assess how well an acupuncture steam-warming eye mask (ASEM) works for individuals with dry eye disease (DED) who use screens frequently, comparing it to a regular steam-warming eye mask (SEM).
- Participants included 40 VDT users with DED, split evenly between the ASEM and SEM groups, and evaluations were done before and after a 2-week treatment period measuring various eye health indicators.
- Results showed significant improvements in the ASEM group regarding subjective symptoms and several eye metrics, indicating that ASEM is more effective than SEM in alleviating DED symptoms and enhancing tear stability for screen users.
