Light Intensity Assessment evaluates the potential health risks associated with exposure to different levels of light intensity in workplaces. This process involves identifying light intensity hazards, assessing the relationship between light exposure levels and health outcomes such as eye strain, fatigue, and disrupted circadian rhythms, estimating the duration and intensity of worker exposure to varying light levels, and characterising the overall risk. Through this assessment, employers and safety professionals can determine whether workplace conditions pose significant risks related to light intensity and to what extent employees might be affected under different exposure scenarios.

Conducting a Light Intensity Assessment is crucial for preventing adverse health effects related to light exposure by identifying and mitigating risks early. It provides the basis for developing lighting management strategies, including proper lighting design, ergonomic adjustments, and scheduling practices, to create a comfortable and safe working environment. Additionally, this assessment guides decision making regarding light control measures, helping prioritize interventions and allocate resources effectively to optimize lighting conditions. It also plays a vital role in educating workers about light intensity risks and promoting practices that support visual comfort and overall well-being in the workplace.
