NCT07340359
This study aimed to evaluate the protective effects of yellow-light etching anti-glare (AG) screen on Digital Eye Strain (DES) induced by prolonged video display terminal (VDT) use under dim environment, Based on the proved positive effect of the circular polarization (CP) screen, providing insights for new eye-protection strategy in the highly digital modern era. In a randomized, double-blind controlled trial, 70 eligible volunteers (diopter ≤ -6.0D; anisometropia ≤ 2.0D) were divided into AG+CP or CP only groups. Participants performed a 2-hour e-book reading task using assigned AG+CP or CP only smartphones. Subjects' severity of DES pre- and post-reading were evaluated from two aspects: the degree of dry eye symptoms and asthenopia. Dry eye symptoms indicators (OSDI, TMH, NIBUT, FBUT, CFS, Schirmer I Test) and asthenopia indicators (CVSS17, Bulbar redness, HFC) were measured and compared.
NCT06589128
Computer vision syndrome (CVS), also referred to as Digital eye strain (DES), is a group of eye and vision problems caused by prolonged use of electronic devices. The American Optometric Association (APA) defines DES as a group of eye and vision-related problems caused by prolonged computer, tablet, e-reader, and cell phone use. Currently, for more than 20 years, DES has been recognised as a public health issue, and the terms DES are also used to describe the condition, attributed to the wide range of digital devices associated with potential problems.
NCT05675475
The goal of this observational study is to determinate the association between DES and changes in binocular vision and ocular surface. in higher education students in the area of health technologies. The main questions it aims to determine the prevalence of Digital Eye Syndrome (DES); the association between DES and changes in binocular vision and ocular surface; whether the time of use and the type of electronic devices influences the degree and type of symptoms of DES; and to determine whether there is an association between the type of ametropia and the symptoms of DES. Participants will have to answer 3 questionnaires (the Computer Vision Syndrome Questionnaire; the Convergence Insufficiency Symptoms Survey, and the Dry Eye Questionnaire (DEQ-5)) and then they will perform an orthoptic assessment and an assessment of the ocular surface with the tear film Break Up Time (BUT) test.
NCT04309097
The primary aim of the current study is to conduct a cluster-randomized control trial to evaluate the effectiveness of a novel digital intervention in reducing anxiety and digital eye strain compared to usual care among Chinese children during the period of home confinement.
