Benjamin Esterman (1906-1994) and the binocular visual field scoring grid that became a world standard for assessing driver eligibility

The visual field grid developed by the ophthalmologist Benjamin Esterman (1906-1994) is today an accepted standard for assessing driver eligibility in many parts of the world. However, little is published about the scientific process that led to the test or about the person who developed it. The aim of this article is to portray the ophthalmologist Benjamin Esterman, and to discuss the visual field grid with his name and its current role in assessing driving eligibility.
