Contrast sensitivity throughout adulthood
Vision Research, 1983Previous studies of spatial contrast sensitivity in adulthood have produced conflicting results. To clarify the situation, we measured contrast sensitivity functions on a large sample of adults (n = 91), ranging in age from 19 to 87. All observers were free from significant ocular pathology and were individually refracted for the test distance ...

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 refers to a measure of how much contrast a person requires to see a target.

Contrast sensitivity in children
Vision Research, 1982We have used a spatial two-alternative, forced-choice staircase technique to measure contrast sensitivities for sinusoidally modulated gratings. Subjects, all of whom were untrained observers, consisted of children of ages 2-16 yr and adults. Our testing method was completely successful with children who were over 3.5 yr but failed with those below 2.5

Contrast sensitivity in dyslexia
Visual Neuroscience, 1995AbstractContrast sensitivity was determined for dyslexic and normal readers. When testing with temporally ramped (i.e. stimuli with gradual temporal onsets and offsets) gratings of 0.6, 4.0, and 12.0 cycles/deg, we found no difference in contrast sensitivity between dyslexic readers and controls.

Contrast Sensitivity After Epikeratophakia
Cornea, 1988Epikeratophakia is a rapidly evolving surgical procedure for the refractive correction of aphakia. Even when Snellen acuity after epikeratophakia is normal, patients often report a subjective degradation of the visual image through the surgically corrected eye.

The Chemistry of Organic Contrast Agents in the NIR-II Window.
Angewandte Chemie, 2021Optical imaging, especially fluorescence and photoacoustic imaging, possesses non-invasiveness, high spatial and temporal resolution, and high sensitivity, etc., compared to positron emission tomography (PET) or magnetic resonance imaging (MRI).
