Abstract

Visual fatigue is a common issue among office workers and can be linked to inadequate lighting conditions; defining what constitutes "inadequate" is crucial for optimal task performance without compromising worker health. A systematic review was conducted using the PRISMA methodology, searching PubMed, SciELO, and Google Scholar to identify studies published between 2020 and 2026. Of the 128 articles identified, seven met the inclusion criteria. The prevalence of visual fatigue ranged from 63% to 80%. While 85.7% of the studies reported lighting levels—generally identifying insufficient or inadequate conditions—none reported the degree of reflection. The results highlight the need for further study into lighting characteristics and their relationship with visual fatigue. Additionally, a lack of studies involving the Mexican population was identified, representing an opportunity for future research.
