About a century a ago, millions of children in the world could stare at the sky at night to see the Milky Way. But as of today, the spectacular view of the universe has been impaired by the use of artificial light at night. The widespread use of artificial light has increased across the globe, especially in urban areas. Thanks to this, light pollution has never been higher.
Light Pollution Types
Skyglow – brightening of the night sky, especially in towns and cities
Glare – excessive artificial brightness, which causes visual discomfort
Clutter – excessively bright and confusing groupings of light sources
Light trespass – light falling where it is not needed<

Prevention Tips
While other types types of pollution are hurdle when it comes prevention, light pollution is easily reversible. This can be done through:
Cut-off – cutting off ensures that light is only directed to where it is needed. Choosing proper exterior light fixtures with cut-off angles helps minimize lighting, improves visibility, and reduces high angle brightness.
Warm-up – this can be done by using LED bulbs and fluorescent lamps, which often produce white warm lighting.
Shielding – Ensure your exterior light fixtures are shielded to prevent directing light to the sky
