Age-related macular degeneration (AMD) is a leading cause of vision loss in Americans aged 60 and older. The loss of central vision from AMD can decrease visual acuity, contrast sensitivity, glare sensitivity, color discrimination, and the ability to adapt to changes in lighting conditions. Older adults with vision loss often have other chronic,…

THE FOLLOWING IS THE FULL TEXT OF THIS DOCUMENT: Video visual aids are Closed Circuit TV systems (CCTV's) which magnify print and enlarge it electronically upon a screen so partially sighted persons with some residual vision can read and write normal size print. These devices are in use around the world in homes, schools, industries and libraries,…

Part of a series of booklets designed to provide practical ideas parents can use to help their children become readers, this booklet focuses on children's eyesight. The booklet's seven sections are as follows: (1) How Does Vision Affect Children's Progress in School? (2) What Kinds of Problems Affect These Demands for Vision? (3) How Can I Spot…

Defined in the booklet is the visually handicapped population that could benefit from use of binoculars, and described with photographs are uses of binoculars and additional equipment. Categories of the visually handicapped and concomitant population sizes are examined to stress the point that approximately 1.64 million Americans are partially…

A comparison study involving 50 second-through-fifth graders was designed to analyze the relationships between the incidence of visual abnormalities and high and low academic achievement. Data suggested that children with deficient visual skills may experience greater problems academically. (SBH)

The article orients the reader to numerous aspects of low vision aids, including types of aids, function of aids, training sequence and considerations, a non-technical description of visual acuity, and favorable prognostic factors in using low vision aids. A brief annotated resource list is included. (Author)

Visual scanning behavior and efficiency of 22 children with visual disabilities and 25 children without disabilities (ages 3.5 to 10 years) were studied. Significant differences were found between groups in length of scan path and number of objects reported, but no significant differences in scanning efficiency. Coordinated binocular eye movements…

The present research investigates newborn infants' perceptions of the shape and texture of objects through studies of the bi-directionality of cross-modal transfer between vision and touch. Using an intersensory procedure, four experiments were performed in newborns to study their ability to transfer shape and texture information from vision to…

We examined 6-month-olds' abilities to represent occluded objects, using a corneal-reflection eye-tracking technique. Experiment 1 compared infants' ability to extrapolate the current pre-occlusion trajectory with their ability to base predictions on recent experiences of novel object motions. In the first condition infants performed at asymptote…

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 paper examines issues concerned with the education and employment of individuals, primarily males, with color vision deficiency. After a brief introduction, the first chapter looks at adult problems such as employment areas in which the disability presents problems. The next chapter considers problems of children, noting the heavy use of color…

Studied were eye coordination and effects of fatigue on vision in the visual and academic functioning of 1049 students in grades 1 through 10. An earlier study (1966) examined the eye coordination of 1152 students in grades 1 through 12. The common Snellen Test of Visual Acuity failed to indicate 42% of students who were diagnosed by other tests…

The article provides information about the number and diversity of preschool children with handicaps requiring vision services, such as refractive errors and eye muscle imbalances, and describes a vision care system designed to ensure that these preschool children receive optimal vision care.
