Abstract
Healthcare professionals are exposed to various intense light sources during dental practice. Of particular concern is blueviolet light (wavelength 380-500 nm), which can impact retinal health, necessitating effective mitigation strategies. In this study, we assessed the practical utility of lenses designed to reduce blue-violet light to wavelengths of approximately 420 nm or shorter within the dental practice setting. Two dentists and four dental hygienists participated in the study. The participants wore either blue-light-reducing lenses or lenses with no effect for one month. The degree of eye strain was evaluated using flicker values. The results revealed that four of the six participants experienced reduced eye strain while wearing blue-violet light-reducing lenses. In conclusion, this study addresses the acknowledged impact of blue-violet light on retinal health. However, the long-term prognosis remains uncertain. Therefore, considering the potential unknown effects, it is necessary to discuss the use of blue-violet light-cut lenses in everyday practice as a risk-management strategy.
