What aspect of lighting does glare primarily affect?

Glare primarily affects comfort and visibility by creating undesirable brightness that leads to discomfort in the visual experience. When bright light is present in a field of vision, it can cause a distracting or blinding effect, making it harder for individuals to see clearly and reducing their ability to perform tasks effectively. This discomfort can lead to visual strain and fatigue, negatively impacting productivity and overall satisfaction with the lighting environment. Therefore, minimizing glare is essential in creating spaces where people can work and move safely and comfortably, enhancing their visual performance and overall well-being.

Color quality, safety of the installation, and energy consumption, while important aspects of lighting design, are not directly impacted by glare in the same way that comfort and visibility are. These factors can influence the overall effectiveness and efficiency of lighting but do not play as significant a role in the immediate discomfort or distraction caused by glare.
