Purpose: The purpose of this study was to determine and compare binocular summation
(BiS) of conventional visual acuity (cVA) versus hyperacuity (hVA) for photopic and scotopic …

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 …

Binocular summation, a well-known phenomenon in letter acuity measurement, refers to the
improvement in visual performance when viewing with both eyes compared to one eye …

Vernier acuity measures the ability to detect a misalignment or positional offset between
visual stimuli, for example between two vertical lines when reading a vernier scale. It is …

Purpose The human eye experiences reduced visual acuity as luminance decreases owing
to reduced retinal and optical resolutions; however, the details are unclear. This study aimed …

Purpose To assess the relationship of binocular visual function tests with binocular
approximations using data from the Collaborative Initial Glaucoma Treatment Study (CIGTS) …

Abstract Purpose: Binocular summation (BiS), defined as the superiority of binocular over
monocular viewing on visual threshold tasks, is most often studied in laboratory settings …

Importance Binocular summation (BiS) is defined as the superiority of visual function for
binocular over monocular viewing. Binocular summation decreases with age and large …

Purpose Although the impact of vision-related quality of life (VRQoL) is assessed optimally
using binocular visual acuity (VA), uniocular VA remains the preferred measurement method …

PURPOSE The purpose of this study was to examine and compare the ability of the Berkeley
Rudimentary Vision Test (BRVT) and the Freiburg Acuity Test (FrACT) to quantify VA in low …
