The impact of excessive artificial light is best understood as contributing to glare, decreasing visibility, and wasting energy. When artificial light is overly bright or poorly directed, it creates discomforting glare that can impair the ability to see clearly. This is particularly problematic in environments where visual acuity is essential, as excessive brightness can lead to confusion in distinguishing objects or navigating spaces.

Additionally, the waste of energy arises from the use of more lighting than necessary for sufficient illumination. This inefficiency not only leads to higher energy costs but also negatively affects the environment through an increased carbon footprint associated with energy generation. The ideal use of artificial light involves optimizing brightness and direction to enhance visibility without contributing to glare or excessive energy consumption.
