A Standardized Arabic Reading Acuity Chart: The Balsam Alabdulkader-Leat Chart

Optometry and Vision Science, 2017
PURPOSE The aim of this study was to develop and validate the first standardized Arabic continuous text near-visual-acuity chart, the Balsam Alabdulkader-Leat (BAL) chart. METHODS Three versions of the BAL chart were created from previously validated sentences.

On the Relationship between Letter Acuity and Reading Acuity

1994
Despite the elemental relationship of letters to written words, letter acuity is well-known to be a poor predictor of several indices of reading performance. This is why direct measurement of reading acuity is necessary in prescription of effective reading aids in low vision rehabilitation.

Age-related changes in baseline reading acuity and speed as measured using RADNER Reading Charts in healthy eyes with best corrected ETDRS distance acuity

British Journal of Ophthalmology, 2018
PurposeTo assess age-related differences in baseline measures of reading performance obtained from the RADNER Reading Charts in healthy eyes with best corrected (ETDRS) distance acuity.MethodsCross-sectional study of participants (n=200) aged 25–74 years (n=20 per 5 years age group).

Evaluating reading acuity and speed in children with microstrabismic amblyopia using a standardized reading chart system

Graefe's Archive for Clinical and Experimental Ophthalmology, 2005
To examine if standardized reading charts with highly comparable test items can be used for evaluating impairments in the monocular reading performance of children with microstrabismic amblyopia characterized by a small angle of squint with less than 5 degrees.The reading performance of 22 children (mean age: 11.7+/-1.6 years) with unilateral ...

Visual Acuity Decrease at Various Illuminations and Role of Reading

Archives of Ophthalmology, 1956
This research was prompted by the lack of quantitative and statistically significant evidence of deterioration of visual acuity in the course of prolonged visual work, despite subjective reports of tiredness. Earlier experimental efforts to produce such evidence were fruitless.* In a previous study 5 it was shown that the course of visual fatigue can ...

A New Reading-Acuity Chart for Normal and Low Vision

Noninvasive Assessment of the Visual System, 1993
Functional measures of visual ability can be of great value in the treatment and care of patients with low vision, or in prescribing optical corrections for patients with normal vision. One such measure is reading ability. We have designed a new reading-acuity chart that is suited for testing observers with normal and low vision.

English sentence optotypes for measuring reading acuity and speed—the English version of the Radner Reading Charts

Graefe's Archive for Clinical and Experimental Ophthalmology, 2014
To develop 28 short sentence optotypes for the English version of the Radner Reading Charts that are as comparable as possible in number and length of words, as well as in difficulty and syntactical construction.Thirty-four English sentences were constructed following the method used for other Radner Reading Charts to obtain "sentence optotypes" with ...
