Contrast sensitivity defines the threshold between the visible and invisible, which has
obvious significance for basic and clinical vision science. Fechner's 1860 review reported …

Spatial contrast is a physical dimension referring to the light-dark transition of a border or an
edge in an image that delineates the existence of a pattern or an object. Contrast sensitivity …

Contrast sensitivity testing is a powerful tool for determining the capability of the visual
system to process spatial and temporal information about the everyday objects we see. The …

How well does a person see faces in a crowd, read a newspaper, or drive an automobile at
night? These are vital questions about a person's quality of life and safety. Obtaining …

A major assumption underlying the use of contrast sensitivity testing is that it predicts
whether a patient has difficulty seeing objects encountered in everyday life. However, there …

The contrast sensitivity function (CSF) predicts functional vision better than acuity, but long
testing times prevent its psychophysical assessment in clinical and practical applications …

A new contrast sensitivity vision chart has been tested and compared to an automated video-
based vision tester on 83 observers whose ages ranged from 9 to 75 years. Good …

A portable microprocessor-controlled instrument automatically measured the static and
dynamic contrast sensitivity functions (CSF's) of 265 observers for a normal population at the …

The ability to distinguish contrast plays an important role in patients' everyday vision.
Contrast sensitivity testing can identify many ocular diseases. Testing the peak of contrast …

Threshold contrast sensitivity functions for 13 subjects were determined on 5 consecutive
days using three psychophysical methods. Each method was implemented on a …
