Optical illusions are mind-bending images that challenge our perception and visual skills. These illusions provide deep ...

In line with the lowered Glx/GABA+ ratio being a compensatory measure to prevent runaway excitation during visual stimulation, the link between the Glx/GABA+ ratio during eye closure and visual acuity ...

Rare individuals treated for congenital cataracts demonstrated shifts in the visual cortex’s excitatory/inhibitory balance even decades post-surgery, reflected by alterations in the neurotransmitter ...

Objectives To estimate the prevalence of poor vision in children aged 4–5 years and determine the impact of visual acuity on literacy. Design Cross-sectional study linking clinical, epidemiological ...

Purpose: Tumbling E is commonly used for visual acuity screening for children and adults. Currently, AAPOS recommends a computerized visual acuity-based screening application JVAS with standardized ...

This study aimed to improve the performance of single-channel steady-state visual evoked potential (SSVEP)-based visual acuity assessment by mode decomposition methods. Using the SSVEP dataset induced ...

When you've completed a visual acuity test, you'll get results as a fraction. The top number refers to the distance you stand from the chart. In most cases, this will be 20 feet.

How to measure distance visual acuity. Community Eye Health. 2014;27(85):16. PMID: 24966459. American Academy of Ophthalmology. What Does 20/20 Vision Mean? American Academy of Ophthalmology. All ...

Figure 2 shows a plot of visual acuity for each eye in different test conditions. It shows whether there is a relationship (i.e., correlation) between visual acuity data in monocular and dichoptic ...
