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…

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…

Optometric disorders are likely to increase the difficulties experienced by an individual who is struggling to read. There are some reports of a higher incidence of visual abnormalities in children with dyslexia, but there has been little investigation into adults. We therefore investigated the optometric status of a population comprising children…

Introduction: This study characterizes self-reported functional vision goals and the use of low vision resources (for example, services and devices) in ophthalmology clinic patients with age-related macular degeneration (AMD) and comorbid depressive symptoms. Methods: From July 2009 to February 2013, we assessed 188 consecutive patients (age 65+;…

In this study, we examined differences in dynamic visual acuity between elite and subelite water polo players and sedentary students. To measure dynamic visual acuity binocularly, we asked participants to indicate the orientation of a broken ring, similar to the Landolt C, which increased in size as it moved across a computer screen. Two different…

This article is an attempt to prepare the ground for the analysis and theorization of the connection between the body and technical devices emerging from miniaturized wearable technologies. The research object is a secular and common "body object," namely, eyeglasses. The article reviews the social history of this artifact and analyzes its…

This fact sheet defines vision, outlines the visual skills needed for school achievement (ocular motility, binocularity, eye-hand coordination skills, and visual form perception), and describes how visual problems are evaluated and treated. The fact sheet also lists clues to look for when a visual problem is suspected, including the appearance of…

This study of the effects of lenses of different colors on the visual abilities and comfort of 20 patients with retinal disease found that, in home trials, the critical issue was density more than color. Office tests of visual acuity and contrast sensitivity with colored lenses did not predict subjective benefit. (Author/JDD)

Describes Intermittent Central Suppression (ICS), a treatable eye malfunction that can make reading difficult. Reports that some students with ICS are not diagnosed through standard vision acuity tests and are misdiagnosed as learning disabled. Presents a study that found that students who were treated for ICS stayed in school longer than students…

Vision of 116 students, ages 6-19, with Down syndrome in the Brisbane (Australia) area was screened. Non-cycloplegic retinoscopy successfully assessed all the students for refractive error. Of the 99 children in special schools, about half did not show significant refractive error but 30 percent were farsighted, 14 percent nearsighted, and 21…

Some cautions regarding the early educational uses of optical aids with visually impaired children are suggested, based on widely held assumptions and recent findings in the fields of perception and reading. The change from the sight conservation era to one advocating the maximum use of remaining vision is traced. (Author/SW)

Low vision children (ages 4-19, n=137) were screened, and 77 percent were advised to have comprehensive clinical evaluations or ophthalmology services. The visual capability of the referred children was determined, low vision aids were prescribed for 56 children, and the degree of successful utilization of aids was evaluated. (JDD)

A task force of opticians and educators in British Columbia was assembled to determine the knowledge and skills required of dispensing opticians and contact lens specialists. The ideas generated by the task force were analyzed and distilled into the standardized tasks listed in this document, using Krathwohl's taxonomy. The document contains 36…

This four-volume student text is designed for use by Air Force personnel enrolled in a self-study extension course for optometry specialists. Covered in the individual volumes are optometry clinic administration (optometry career and field training, ethical relationships and professionalism, eligibility for optometric care and appointment…

This course is designed to help military personnel to attain the rating of optometry specialist in the Air Force. The packet includes both a teacher's plan of instruction and five student study guides/workbooks. The teacher's plan of instruction contains lesson plans, lists of student instructional materials and audiovisual aids, and suggested…
