Contrast sensitivity

Ophthalmology Clinics of North America, 2003
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, 1982
We 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, 1995
AbstractContrast 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, 1988
Epikeratophakia 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.
