The Development of a Precision Series of Landolt Ring Acuity Slides.

Abstract

The need for the development of improved methodologies for the assessment of the visual capabilities of naval aviation personnel has led to the development of the NAMRL Vision Test Battery. Test stimuli were not available which could meet the requirements for these visual measurements. The problem addressed within this report is the specification, production duplication and implementation of a series of high resolution test targets adequate to perform this task. Alternative methods of presenting visual tests stimuli were investigated. Optical projection was chosen over hard copy charts or CRT displays. The Landolt ring was selected as the primary stimulus pattern in agreement with the International Ophthalmological Congress of 1909. Projection slide series with geometric progression in size were specified and produced under rigorous quality control. In order to facilitate correct use of the target series, a systematics nomenclature, conversion tables, nomographs and instructions, for their use were developed. The slides have been designated the Morris-Goodson series.
