Glare points are the intensity maxima seen when a water drop illuminated by a wide beam is viewed from a certain direction and imaged. We show that good resolution in both the scattering angle and the glare point position can be achieved only if the size parameter x = 2pia/lambda is >>1 and that the positions of the glare points can be computed by a ...

The control of high-speed aircraft is a demanding task in which rapid decisions, based on visually acquired information, must frequently be made. Glare, both direct and veiling, is a prime cause of visual degradation in flight. The visual effects of glare are discussed together with means of reducing its consequences.

Abstract The glare effect consists in a strong brightness enhancement of a bright region determined solely by the presence of linear luminance gradients organized in such a way that the bright ends of the gradients delimit the bright region. The effect is obtained with both achromatic and chromatic gradients.

Brightness of the glare illusion
Proceedings of the 5th symposium on Applied perception in graphics and visualization, 2008The glare illusion is commonly used in CG rendering, especially in game engines, to achieve a higher brightness than that of the maximum luminance of a display. In this work, we measure the perceived luminance of the glare illusion in a psychophysical experiment.

Glare is regarded as a sensation produced by light which enters the eye in such a fashion as to inhibit distinct vision. When this light is superimposed upon a retinal image, glare reduces contrast and is called veiling glare. When luminance levels are very high, glare may have dazzling effects (dazzling glare), and when intense directed light reduces ...

Abstract To describe the effect of glare on visibility Holladay (1927) and Stiles (1929) used an equivalent background luminance β given by the formula β = B +kEθn in which B is the actual background luminance, E is the glare illumination at the observer's eye, and θ is the angle of the glare source from his line of sight. The use of the formula is

Effect of Sunglasses on Visual Detection under Conditions of Glare and No Glare
Perceptual and Motor Skills, 1963This experiment tested the effect of sunglass usage on visual detection efficiency under conditions of glare and no glare. Ss were given the task of determining the presence of a spot on a field of moderate illumination in a dark room and in the same room with the addition of glare produced by two flood lights.

The Glare Effect and the Perception of Luminosity
Perception, 2001The impression of self-luminosity in the glare effect was studied in two experiments. In experiment 1 the target (CS) was set to the highest luminance of the field and subjects were asked to adjust the luminance ramp of the inducers (R) against five backgrounds (B) to the point where they began to see CS as self-luminous.

Abstract The re-adaptation times of observers subjected to white and yellow glare of equal luminance have been measured. Some eighty-three observers took part within an age range 17–66 years. There is found to be a positive correlation between re-adaptation time and age in both illuminants. There is some evidence to suggest that, particularly for the
