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…

Introduction: Eccentric viewing training has been a strategy, used by rehabilitation professionals, to help individuals with central vision loss move their eyes in such a way that they focus the incoming light on parts of the retina located away from the center area that has been damaged and improve visual functioning. A number of studies have…

Far too often, professionals focus almost solely on individuals' needs for magnification level for reading. Visual acuities are measured and decisions are made for low vision devices largely on the basis of acuity levels. Contrast sensitivity function is often overlooked as a critical need for and predictor of the selection and preference for low…

This study investigated peripheral vision (at least 30[degrees] eccentric to fixation) development in profoundly deaf children without cochlear implantation, and compared this to age-matched hearing controls as well as to deaf and hearing adult data. Deaf and hearing children between the ages of 5 and 15 years were assessed using a new,…

This article provides a terminological framework to show the relationships among different types of visual deficits. It distinguishes between visual functions, which describe how the eye and the lower visual system function, and functional vision, which describes how a person functions. When visual functions are disturbed, the term "visual…

The system described represents a new technique for enhancing the fidelity of flight simulators during high acceleration maneuvers. This technique forces the simulator pilot into active participation and energy expenditure similar to the aircraft pilot undergoing actual accelerations. The Bionic Control of Acceleration Induced Dimming (BIOCONAID)…

Early detection of significant vision problems in children is a high priority for pediatricians and school nurses. Routine vision screening is a necessary part of that detection and has traditionally involved acuity charts. However, photoscreening in which "red eye" is elicited to show whether each eye is focusing may outperform routine acuity…
