Contrast Sensitivity Function for Stereopsis
Perception, 1978Contrast thresholds for stereopsis from narrow-band-filtered random-dot stereograms were compared with contrast thresholds for simple detection of similar narrow-band noise. Centre frequencies of filters were in the range 2·5–15 cycles deg−1. It was found that the contrast sensitivity function for stereopsis is similar in shape to that for detection ...

Contrast Sensitivity Function in Nephropathic Cystinosis
Archives of Ophthalmology, 1987Cystinosis is a rare autosomal recessive metabolic disorder in which nonprotein cystine accumulates within most body organs due to a defect in lysosomal cystine transport. The pathognomonic ocular manifestations of cystinosis are the presence of distinctive iridescent crystals within ocular tissue and a pigmentary retinopathy.

Rapid Measurement of Contrast-Sensitivity Functions
Optometry and Vision Science, 1977We have developed a reliable and valid procedure for determining a person's contrast sensitivity function in approximately 6 min. This rapid procedure, which resembles that used in the Bekesy sweep-frequency audiometer, has potential as a clinical tool for diagnostic assessment.

The Contrast Sensitivity Function and Childhood Amblyopia
American Journal of Ophthalmology, 1987We measured contrast sensitivity function and visual acuity in both eyes of strabismic and anisometropic amblyopic patients. There was a linear relationship between contrast sensitivity function and visual acuity in the amblyopic eye. As visual acuity decreased, the contrast sensitivity function decreased along the contrast sensitivity axis, and peak ...

Normative Contrast Sensitivity Functions
Optometry and Vision Science, 1987Sixty college age observers who were prescreened for 6/6 (20/20) acuity were examined twice on an automated contrast sensitivity system. A significant practice effect was evident in the obtained contrast sensitivity functions (CSF's). In addition, marked differences were found between the contrast sensitivity scores in the present work and the ...

1984
The contrast sensitivity function is a normalised description of a system’s sensitivity to spatial frequencies in terms of the contrast required to perform some perceptual task. For detection tasks, the human C.S.F. peaks at around 3–5 cycles/deg and reaches zero at about 60 cycles/deg. See modulation transfer function .

Contrast Sensitivity and Functional Vision
International Ophthalmology Clinics, 2003How 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 answers to these questions requires tests of functional vision.

Contrast Sensitivity during Horizontal Visual Pursuit: Dynamic Sensitivity Functions
Perception, 1992The contrast sensitivity functions of college students for grating targets presented at angular velocities of 0, 30, 60, and 90 deg s−1 were determined for target durations of 200 and 600 ms. The most pronounced effects of target movement were evident at the mid to high spatial frequencies in which sensitivity was markedly reduced as velocity ...

Vision Evaluation Using Contrast Sensitivity Functions
Optometry and Vision Science, 1983The use of Contrast Sensitivity Functions (CSF's) in vision evaluation has been explored for several years. Although theoretically superior to Snellen acuity and similar measures, the use of CSF is not widespread. A review of some of the clinical conditions in which CSF's have been used is followed by a discussion of the problems involved in their ...

Contrast sensitivity function and image discrimination
Journal of the Optical Society of America A, 2001A previous study tested the validity of simulations of the appearance of a natural image (from different observation distances) generated by using a visual model and contrast sensitivity functions of the individual observers [J. Opt. Soc. Am. A 13, 1131 (1996)].
