What phenomenon is caused by too much or uneven light on a field?

Glare occurs when there is an excessive amount of light, or when the light is unevenly distributed on a field, creating discomfort or visibility problems for players and spectators. This phenomenon can impair a person's ability to see clearly, making it challenging to focus on the action taking place. It is particularly detrimental in sporting events, where players need to maintain their attention on fast-moving elements, such as a ball or other participants, and spectators require clear visibility to enjoy the experience.

The impact of glare can affect performance and safety, as it may hinder the ability to judge distances and movement accurately. Designing lighting systems that minimize glare is critical for enhancing the experience in outdoor and indoor sporting facilities. This can involve using fixtures that direct light appropriately, ensuring an even distribution across the field or court, and adjusting light intensity levels to suit the activity.

In contrast, the other terms relate to different concepts in lighting and vision. Sky glow refers to the brightening of the night sky due to artificial light pollution; trespass pertains to unauthorized intrusion onto a property; and diffuse reflection involves light scattering in many directions after hitting a surface. While these phenomena are relevant to discussions around lighting, they do not specifically address the discomfort or visibility issues created by excess or uneven light, which
