Purpose To evaluate the agreement between subjective high and low contrast visual acuity
(VA) and predicted values from double-pass system measurements in healthy candidates to …

Abstract The measurement of Contrast Visual Acuities (contrast VA) is recognised in various
studies as an important psychophysical measure of visual function, and contrast VA is often …

Purpose: The aim of this study was to determine the repeatability of high‐and low‐contrast
visual acuity (VA) measurements at near. Methods: Fifty‐five normal subjects were recruited …

Purpose This study reports contrast sensitivity (CS) reference values obtained by two
different test methods in a strictly selected population of healthy, young adults with normal …

Purpose: Contrast sensitivity can be an asset and “true” representation functional vision
when compared to visual acuity measured using the high contrast Snellen or ETDRS acuity …

Purpose: To evaluate a newly designed computer-based test system for the measurement of
contrast thresholds at different luminance levels. Methods: The FF-CATS is a psychophysical …

Purpose: To assess the agreement between two different contrast testing modalities using
the index of contrast sensitivity (ICS) in patients with low vision. Methods: Thirty-eight …

Purpose: Clinically a quick and reliable estimate of contrast sensitivity levels is desirable to
evaluate patients with decreased vision or difficulty of vision in dim illumination. The Evans …

Purpose To test an automated, tablet‐based self‐testing method for the determination of low
contrast near visual acuity in ophthalmic patients. Methods The Mobile Assessment of Vision …

Visual system transfers information at both high and low contrastlevels. It has been
customary to assess visual function by measuring visual acuity although it has been well …
