Mexico City at night, showing skyglow A map from 1996 to 1997 showing the extent of skyglow over Europe. Skyglow (or sky glow) is the diffuse luminance of the night sky, apart from discrete light sources such as the Moon and visible individual stars. It is a commonly noticed aspect of light pollution.
Adjusting the type of lights used, so the light waves emitted are those that are less likely to cause severe light pollution problems. Mercury, metal halide and above all first generation of blue-light LED road luminaires are much more polluting than sodium lamps: Earth's atmosphere scatters and transmits blue light better than yellow or red light.
Light pollution, the term for the brightening of the night sky by unnatural lights, is increasing worldwide. On average, skies are getting 10% brighter each year globally, with the fastest rate of ...
Turn down dashboard lights to reduce glare. Wear prescription glasses with an anti-reflection coating. Keep blinking while driving to ward off dry eye symptoms.
If light sources (e.g. the Moon and light pollution) were removed from the night sky, only direct starlight would be visible. The sky's brightness varies greatly over the day, and the primary cause differs as well. During daytime, when the Sun is above the horizon, the direct scattering of sunlight is the

Light ergonomics is the relationship between the light source and the individual. [1] Poor light can be divided into the following: Individual or socio-cultural expectations; Insufficient light; Poor distribution of light; Improper contrast; Glare; Flicker; Thermal heating (over or under) Acoustic noise (especially fluorescents)
