In crowding, the perception of a target strongly deteriorates when neighboring elements are
presented. Crowding is usually assumed to have the following characteristics.(a) Crowding …

Purpose Children may be tested with a variety of visual acuity (VA) charts during their
ophthalmic care and differences between charts can complicate the interpretation of VA …

Crowding refers to the degradation of visual acuity for target optotypes with, versus without,
surrounding features. Crowding is important clinically, however the effect of target-flanker …

PURPOSE The purpose of this study was to investigate the development of visual acuity
(VA) and contrast sensitivity in children as measured with objective (sweep visually evoked …

The current review aimed to collect and critically analyze the scientific peer-reviewed
literature that is available about the use of digital applications for evaluation of visual …

Mobile technology is increasingly used to measure visual acuity. Standards for chart-based
acuity tests specify photometric requirements for luminance, optotype contrast and …

Visual acuity can be measured in many different ways, including with letters and Vernier
offsets. Prior psychophysical work has suggested that the two acuities are strongly linked …

Our ability to select relevant information from the environment is limited by the resolution of
attention–ie, the minimum size of the region that can be selected. Neural mechanisms that …

The effects of text display, specifically within-word spacing, on children's reading at different
developmental levels has barely been investigated. This study explored the influence of …

Purpose: To evaluate whether computerized training with a crowded or uncrowded letter-
discrimination task reduces visual impairment (VI) in 6-to 11-year-old children with infantile …
