Discomfort glare is a psychological sensation caused by high brightness (or brightness contrast) within the field of view, which does not necessarily impair vision. [2] In buildings, discomfort glare can originate from small artificial lights (e.g. ceiling fixtures) that have brightnesses that are significantly greater than their surrounding.
The glare makes the image look "washed out" by reducing contrast and color saturation (adding light to dark image regions, and adding white to saturated regions, reducing their saturation). Visible artifacts, usually in the shape of the aperture made by the iris diaphragm , are formed when light follows a pathway through the lens that contains ...
Last year, the U.S. began allowing a headlight technology to improve nighttime visibility and reduce glare. But there are still no vehicles with it for sale.
Front lighting is also quite common, but tends to make the subject look flat as its casts almost no visible shadows. Lighting from the side is the less common, as it tends to produce glare near eye level. Backlighting either around or through an object is mainly for accent. Backlighting is used to illuminate a background or backdrop.
Eliminate or Reduce Glare. Look for driving sunglasses with polarized lenses and an anti-reflective (AR) lens coating. Polarization filters glare from reflections: off other cars, buildings, roads ...
Ocular straylight is a phenomenon where parts of the eye are able to scatter light, creating glare. It is analogous to stray light in other optical systems; scattered light reaches the retina, but does not contribute to forming a correct image. One can observe the effect of straylight by looking at a distant bright light source against a dark ...
To earn and keep the certification, it retrofitted thousands of lights to reduce glare and shine downward, and maintains a certain level of sky quality. It is among 148 dark sky places in the U.S ...
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)
