Purpose It is well established that visual acuity (VA) decreases with luminance but the
specific factors that are responsible remain unclear. The purpose of this study was to …

Purpose To determine the repeatability of mesopic high-contrast (HC) and low-contrast (LC)
visual acuity (VA) measurements made at distance and near in healthy young individuals …

To evaluate mesopic functional visual acuity (FVA) with a newly developed system in normal
subjects and to compare the results with photopic FVA, sixty-eight healthy volunteers …

Purpose.: To determine photopic and mesopic distance high-contrast visual acuity (HC-VA)
and low-contrast visual acuity (LC-VA) in eyes with early age-related macular degeneration …

ABSTRACT PURPOSE: To develop s ingle-valued wavefront aberration metrics that
correlate strongly with visual performance. The purpose of this study is to explore whether …

Aim Although contrast vision is not routinely tested, it is important: for instance, it predicts
traffic incidents better than visual acuity. Mesopic contrast sensitivity (CS) testing …

The spectral sensitivity of the eye at low light levels, ie, mesopic conditions, is determined by
the rod and cone photoreceptors of the retina operating together in varying degree as …

Purpose Visual acuity (VA) is an important determinant of visual function. Here we establish
procedures and recommendations for VA testing extending beyond the classical VA and …

Background Hitherto recommendations and thresholds for contrast tests are available for
mesopic but not for photopic methods. While mesopic tests are widespread in …

Purpose The decrease in visual acuity under low luminance conditions is well known.
Recent laboratory evidence showed that crowding under low luminance (mesopic) light …
