Reading errors made by children with low vision.
Previous research has shown that, on average, children with low vision lag their sighted peers in general reading development (in terms of speed, accuracy and comprehension). This study sought to examine this apparent lag by comparing the reading profiles of 25 normally sighted readers (mean age 8 years 8 months) with 25 low vision readers. The children were tested using a reading test (the Nea...
متن کاملPsychophysics of reading--II. Low vision.
Very little is known about the effects of visual impairment on reading. We used psychophysical methods to study reading by 16 low-vision observers. Reading rates were measured for text scanned across the face of a TV monitor while varying parameters that are likely to be important in low vision: angular character size, number of characters in the field, number of dots composing each character, ...
متن کامل[Evaluation of patients using an innovative low-vision aid].
PURPOSE To perform a preliminary evaluation at the "Clínica Oftalmológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (USP)" of an innovative equipment for low-vision developed at USP containing a reading stand and a magnifier that maintains in a stable position the reading line and focus. METHODS 9 low-vision patients were evaluated using the above mentione...
متن کاملLow Vision Aid through Laser Retina Imaging
Laser retina imaging technology enables creation of a clear picture in any retina area. It is focus-free, i.e. irrelevant of refractive disorder. So in many cases of low vision, one can see the picture by one’s own eyesight. In this article we describe possible applications of this emerging technology, including 1. Development of eyesight-aid for low vision, an HMD (headmounted display) on whic...
متن کاملDetermining magnification for reading with low vision.
BACKGROUND In the past, practitioners have used distance and/or near visual acuity (VA) to calculate required magnification for low vision aids. Magnification was usually under-estimated when compared with the final magnification prescribed. Recent studies have emphasised the importance of acuity reserve in determining the required magnification for optimum reading rate. Two different approache...
