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…

The burden of childhood visual impairment and disparities in access to pediatric vision care remain pressing issues in the United States. School-based vision programs (SBVPs) serve as one approach to advancing health equity. Operating at the intersection of schools and healthcare, SBVPs can increase access to pediatric vision services, improve…

Background: Reading failure is far higher among disadvantaged students than among other students (National Center for Education Statistics, 2019). Many attempts to solve this have focused on schools, yet non-school factors have a substantial impact on learning (Clabaugh, 2008). One of these is uncorrected vision. Approximately 20-25% of school-age…

Annual health checks for people with learning disabilities are a concept that was introduced by the Government in 2001 as a catalyst to improve access to health services and identify health needs that have previously gone undetected. Nonetheless, to date, there has been little evidence of the effectiveness of these health checks. This study seeks…

The study assessed the effectiveness of a pilot intervention to promote the use of eyeglasses in one school in California. The intervention used a one-group pretest, posttest design. Between January and June 2011, during the intervention, all first- and second-grade children received eye evaluations and the children with refractive error received…

We explored mediating concepts that affect clinical novices shifting between their talk "with" patients in eye examinations and their talk "about" patients in case presentations (nCPs). In a Canadian optometry teaching clinic, patient "chief concern or request", "illness experience", and…

The most commonly used chart for testing eye acuity is the Snellen Chart, developed more than 100 years ago. A description is given of the way this chart works, its uses, and its limitations. (JD)

The eyes are the most complex organs in the body. Children's eyes are still developing until they are around 8-9 years old; therefore it is important to check that they are working properly before it is too late to rectify any problems. So how do they work, and why do they sometimes go wrong? In this article, the author explains children's eye…

The role of optometry in the study of learning difficulties and the problems of interpreting research results in the fields of optometry and ophthalmology are discussed. Limitations of school visual screening are described, and it is suggested that many children with learning difficulties should be referred for a full clinical visual examination.…

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…

An inexpensive computer graphics systems (Commodore PET), used as a video aid for teaching students advanced case analysis, is described. The course provides students with the analytical tools for evaluating with graphical and statistical techniques and treating with lenses, prisms, and orthoptics various anomalies of binocular vision.

The interview with G. N. Getman, a developmental optometrist specializing in learning problems and disabilities, focuses on vision's impact on learning, the role of the vision specialist in the remediation of learning problems and disabilities, early screening programs, and visual training programs. (DLS)

This discussion of factors to consider in planning a successful public presentation highlights multimedia presentations; verbal skills; proper use of visual materials; an explanation of vision measurements; lettering size and style; screen size; level of illumination; and machine handling. (LRW)

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…
