Abstract
|
|
|
Purpose: This review aimed to examine the effects and symptoms of using digital devices on the eyes, and ways to improve digital eye strain (DES).
Methods: We did a comprehensive search using PubMed, Google Scholar, and RISS(Research information sharing service) for available literature related to DES.
Results: DES symptoms may be divided into external symptoms related to dry eye and internal symptoms linked to refractive errors, accommodative or vergence problems. These symptoms require management to promote a comfortable visual life. Questionnaires are used for evaluation and treatment of DES, and indices of visual fatigue may be provided through objective evaluation of parameters such as critical flicker-fusion frequency (CFF), blink rate and completeness, accommodative function, and pupil characteristics.
Conclusions: In order to improve DES, various approaches may be selected including frequent blinking, correction of refractive error and presbyopia, reducing average daily screen time, management of dry eye, regular screen breaks, and consideration of accommodation and vergence anomalies. In addition, clinical practitioners should be able to provide information pertaining to proper use of digital devices and ergonomic awareness related to public health.
