Introduction: The Newborn Acuity Cards (NAC) have been used on neonates and were noted to be simple, fast, and reliable. The distinguishing features of NAC include central placement of the gratings and wide range of grating acuity that can be measured. In the current study, NAC were used with children who had developmental delays to determine the…

Visual system is crucial to autobiographical memory. Research tended to show that blind adults may compensate for the loss of visual information in retrieval of their autobiographical memories. Much less is known about how blind children's autobiographical memory develops in the absence of visual information. Using cue-word methodology, 36 sighted…

The limitation of conventional visual acuity assessment, which primarily focuses on individual eye performance (monocular visual acuity tests). This study addresses this limitation by emphasizing the importance of binocular vision, where both eyes work together. Binocular vision provides numerous advantages, such as improved depth perception, a…

Introduction: This study aims to assess the prevalence of visual impairment and refractive error among learners who are deaf or hard of hearing in schools for Deaf students in Ghana. Methods: A descriptive cross-sectional study design was used to assess the distance visual acuity with the logMAR "E" chart, and ocular health was assessed…

The topic of this study was to provide a description of instruction identified and provided by teachers of students with visual impairments. It was not known how teachers describe vision interventions, environmental adaptations, and educational modifications for students with cortical visual impairment. The study was conducted in Southwest…

This cross-sectional study aimed to investigate developmental changes in the efficiency of sustained, selective, and divided attention in a group of children aged 6-12 years by means of a computerized test battery. Participants included 199 children (51% female, majority White) who had normal or corrected-to-normal vision and no history of either…

This study investigates the individual difference antecedents of students' behavioural intention to use VR-based learning systems, especially from an integrated perspective of Big Five personality traits and perceived physiological vulnerability to IT use (PPVITU). Data collected from 149 respondents are tested against the research model using the…

Blind adults display language-specificity in their packaging and ordering of events in speech. These differences affect the representation of events in "co-speech gesture"--gesturing with speech--but not in "silent gesture"--gesturing without speech. Here we examine when in development blind children begin to show adult-like…

The eye should have a particular focal length in order to see an object. As there are many things to see, the focal length of the eye must vary because these things are not all at the same distance from the eye. We explore the eye accommodation from a geometrical optics point of view and present our results in this paper; the study includes a…

During the 2020-21 academic year, COVID-19-related educational disruptions impacted school-based vision screenings. However, limited information regarding changes in vision screening and the number of students impacted has been reported. Delayed screenings can negatively impact students' referral to eye care providers, which may affect a child's…

Vision classification tasks, a fundamental and transformative aspect of deep learning and computer vision, play a pivotal role in our ability to understand the visual world. Deep learning techniques have revolutionized the field, enabling unprecedented accuracy and efficiency in vision classification. However, deep learning models, especially…

The goal of this study is to assess the referral rate accuracy of photoscreening versus the chart methodology in identifying preschool children at risk of amblyopia and amblyogenic refractive error. Vision screenings using the plusoptiX S12 and the LEA chart were performed on 127 children, aged 3-5 years old. Comprehensive eye exams were performed…

Introduction: Past studies have provided evidence that the effects of tactile stimulation on binocular rivalry are mediated by primitive features (orientation and spatial frequency) common in vision and touch. In this study, we examined whether such effects on binocular rivalry can be obtained through the roughness of naturalistic objects. In…

Specific learning disabilities affect the brain's ability to process verbal and non-verbal information efficiently and accurately. The most common learning disability is reading disability which includes dyslexia. Evidence supports that dyslexia is a language-based disorder. The core deficit of dyslexia is the phonological component of language…

This study investigated the self-concept of students with vision impairments who were placed in mainstream and specialist schools in South Australia. Self-Concept was studied across six dimensions, namely Physical, Moral, Personal, Family, Social and Academic Self-Concepts and the Total Self-Concept. The 'Tennessee Self-Concept Scale: Second…
