Impairment of contrast vision

Тодорхойлолт

Contrast sensitivity refers to the ability to distinguish small differences in brightness between adjacent surfaces. Peak Contrast sensitivity refers to the smallest differences that are discernible for large stimuli. For smaller objects, such as those involved in many Activities of Daily Living, contrast sensitivity interacts with visual acuity and visual field. Better contrast makes smaller details visible. The visual field is larger for stronger stimuli.
