Development and Validation of a Smartphone-Based Visual Acuity Test (Peek Acuity) for Clinical Practice and Community-Based Fieldwork. [PDF]
JAMA ophthalmology, 2015 IMPORTANCE: Visual acuity is the most frequently performed measure of visual function in clinical practice and most people worldwide living with visual impairment are living in low- and middle-income countries.

Investigative Opthalmology & Visual Science, 2018 Dry eye (DE) causes irregularity of the ocular surface and reduces the quality of vision. An intact, regular tear film is essential for high-quality retinal images; however, visual tasks requiring sustained gazing can disrupt the tear film, eventually degrading visual function.

Prevalence of Visual Acuity Loss or Blindness in the US
JAMA ophthalmology, 2021 Key Points Question How many people in the US are living with uncorrectable visual acuity loss or blindness? Findings This bayesian meta-analysis generated an estimate that, in 2017, there were 7.08 million people living with visual acuity loss, of whom ...

Asymmetries in visual acuity around the visual field
Journal of Vision, 2020 Human vision is heterogeneous around the visual field. At a fixed eccentricity, performance is better along the horizontal than the vertical meridian and along the lower than the upper vertical meridian.

Finely tuned eye movements enhance visual acuity
Nature Communications, 2020 High visual acuity is essential for many tasks, from recognizing distant friends to driving a car. While much is known about how the eye’s optics and anatomy contribute to spatial resolution, possible influences from eye movements are rarely considered ...

VEP estimation of visual acuity: a systematic review
Documenta Ophthalmologica, 2020 Purpose Visual evoked potentials (VEPs) can be used to measure visual resolution via a spatial frequency (SF) limit as an objective estimate of visual acuity.

Visual Acuity does not Moderate Effect Sizes of Higher-Level Cognitive Tasks. [PDF]
, 2016 Background/study contextDeclining visual capacities in older adults have been posited as a driving force behind adult age differences in higher-order cognitive functions (e.g., the "common cause" hypothesis of Lindenberger & Baltes, 1994, Psychology ...

Dysflective cones: Visual function and cone reflectivity in long-term follow-up of acute bilateral foveolitis. [PDF]
, 2017 PURPOSE:Confocal adaptive optics scanning laser ophthalmoscope (AOSLO) images provide a sensitive measure of cone structure. However, the relationship between structural findings of diminished cone reflectivity and visual function is unclear.
