The most common impact is that it changes another person’s quality of life. For example, it might be disturbing someone else’s sleep pattern with a strong bright light that shines directly into their room at night.
A common effect on city areas, it becomes more difficult to appreciate nature when this artificial light reduces the natural brightness of the moon and the stars. In addition, there is the element of energy being wasted.
In countries like US, UK and even Singapore, huge quantities of fossil fuels are used to provide sufficient energy for lighting up the city.
Prolonged exposure to artificial light also affects our vision especially with poor management and control.
