Dark Sky & Light Pollution - Learning Objectives
When we use carefully aimed, dimmer lights - instead of excessively bright, glaring ones - we can see better, maybe even see the stars. Balance and restraint is the key to most things in life, and restraint also applies to lighting, especially in our night sky.

What is Dark Sky and why is it important?
How could the sky at night be anything other than dark? It seems like an easy question, until you look up and try to see the Milky Way in or near a large city.
If you want to see stars, you need a dark scene free from overhead lights and free from light pollution.
Light Pollution is the name for any light that is unwanted or uncontrolled showering wasted light into the sky. Reflected light from pavement and buildings is also contributing to light pollution.
Direct Glare from unshielded light sources reduces visibility in addition to requiring your eyes to adapt between bright and dark scenes, especially difficult for seniors and those with visual impairments. As we age the time it takes for our eyes to adapt from bright to dark, or dark to light, increases.; therefore, illumination without direct glare from seeing the light source is preferred.
