OCULUS Ishihara Tests
Description
Ishihara Tests for Color Deficiency provide a quick and accurate assessment of congenital color blindness, the most common form. The Ishihara charts distinguish between total color blindness and strong and mild forms of both protan and deutan color defects. A guide to the use and interpretation of the color charts is provided in English. Used by ophthalmologists, opticians, primary care and occupational health practitioners.
The 38-plate (Complete) Edition is used principally by Ophthalmologists to define the type of color deficiency.
The 24-plate (Abridged) Edition is used principally at airports, Local Government Offices, Recruitment Agencies, Factories and other business' concerned with conducting sample surveys for color deficiency in a short space of time or when hiring new employees.
The 14-plate (Concise) Edition comprises a selection of charts from the 38-plate version to give the highest accuracy possible from a minimum set of plates.
The 10-plate for Unlettered Persons Edition is for the testing of children below school age or unlettered persons. In this edition, the figures are expressed as circles and squares or a winding line to be traced.
