説明

Visual function of low-vision individuals is influenced by the illuminance of the viewing environment and the luminance of the object being viewed. In this paper, we will give an overview of contrast sensitivity and color similarities and the effects of luminance and illuminance on visual function. Low-vision individuals, who have reduced visual functions compared to sighted persons, have even lower sensitivity to contrast and ability to distinguish colors under mesopic light conditions. Majority of test subjects surveyed reported experiencing glare during the day in their daily activities. Thus, lighting considerations for low-vision individuals should not only include darkness but also glare.
