ASF 38 Plates Ishihara Color Blindness Test Book

The ASF 38 Plates Ishihara Color Blindness Test Book is a diagnostic tool designed for the accurate assessment of congenital color vision deficiencies, particularly red-green blindness. This widely recognized test is utilized by optometrists and ophthalmologists globally to identify and classify color vision defects. The test employs a series of 38 pseudo-isochromatic plates, each featuring colored dots arranged to conceal numbers or patterns visible to individuals with normal color vision, but difficult or impossible for those with red-green color vision deficiencies to discern.

Manufactured by ASF Universal, an ISO 9001:2015 certified company, this test book is constructed with high-quality coated paper plates encased within a durable, rectangular, blue hardbound album-type cover for ease of handling and longevity. The book, weighing 250g, is designed for professional use in clinical, educational, and training environments, providing a reliable method for screening protanopia, deuteranopia, and other color deficiencies.
