In this context, it is necessary to conduct further research seeking to refine the sample characteristics to establish intra and more homogeneous parameters between groups and thus further elucidate the effect of chronic alcohol use on visual perception of achromatic luminance contrast.
It is widely believed that the human visual system (HVS) is more sensitive to local luminance contrast than pixel values or luminance.
Confusion colours must be carefully selected and luminance contrast clues eliminated.
Therefore, an analysis of these contrasting results and the frequency-specific effect of aging on contrast sensitivity (Figure 2) might show that human aging distinctively affects luminance contrast processing in the magno and parvocellular pathways.

So colour or orientation contrast; luminance contrast in terms of light and dark things that pop out.
Spatial luminance contrast sensitivity tests of macaque and human observers.
Second, our manipulation optimized luminance contrast in the nighttime condition and did not include the detrimental effects of nighttime driving, such as increased glare and a reduction in overall luminance, both of which can affect older drivers in particular.
Property designers can select materials to enhance or minimize luminance contrast depending on the effect they are trying to achieve.
QD Vision will leverage its leadership in quantum-dot materials and deposition techniques to develop micro-displays that feature high luminance contrast, saturated colors, and improved distinction and resolution of color coded data.
The light was frequently aimed at the ceiling to reduce glare, an early example of indirect lighting, a technique still employed today to reduce luminance contrast and enhance visual comfort.
