The use of digital devices in daily work activities has increased, particularly in information technology-based companies. Prolonged use of computers and laptops may increase visual workload and contribute to various eye health complaints known as Digital Eye Strain (DES) or Computer Vision Syndrome (CVS). This study aimed to describe digital light exposure and its impact on workers' eye health at NTT Data. This study employed a qualitative descriptive design. Data were collected through in-depth interviews and observations involving 10 informants, consisting of 8 primary informants, 1 supporting informant, and 1 key informant. Data credibility was established through source and method triangulation, while data were analyzed using the Miles and Huberman model. The results showed that digital device use among workers was relatively high, with a daily duration of approximately 6–9 hours. Of the 10 informants, 6 reported eye health complaints, while 4 reported no significant complaints. The reported complaints included eye fatigue, eye irritation, watery eyes, eye redness, blurred or double vision, and glare. These complaints were found among workers with high levels of digital device use and were associated with eye-rest habits and workplace ergonomics. The preventive measures practiced by workers included resting their eyes, using eye drops, wearing glasses as needed, adjusting screen brightness, and maintaining an ergonomic working position. The company also provided support through ergonomic work facilities, periodic health examinations, eyeglass reimbursement, eye-drop coverage, health insurance, and occupational health and safety education. However, there was no specific program focusing on the prevention of eye health problems related to prolonged digital device use. This study indicates that prolonged digital light exposure is associated with the occurrence of various eye health complaints among some workers at NTT Data.
