Ishihara® 1254 Test Chart Books – Globally Accepted Plates for Red-Green Color Blindness Detection

The Ishihara® Test Chart Books (published by Kanehara Trading Inc., Tokyo, Japan – exclusive North American distributor: Graham-Field / Ishihara) are the worldwide gold standard for simple and accurate detection of congenital color vision deficiency, particularly red-green blindness (the most common form, ~99% of cases). Developed by Dr. Shinobu Ishihara in 1917, these pseudoisochromatic plates exploit the fact that blue and yellow appear remarkably bright compared to red and green in red-green deficient individuals. Each edition includes four special diagnostic plates to determine the type and degree of defect. Plates are encased in a durable, album-style book for easy handling and protection. Detailed instructions are included. Ideal for ophthalmology, occupational health screening (aviation, military, driving), schools (especially the 10-plate edition for children/unlettered persons), and general clinical use.
