Ishihara Color Deficiency Test Book (38 Plates) - A Comprehensive Tool for Detecting Color Vision Deficiency

Overview: The Ishihara Color Deficiency Test Book (38 Plates) is an authoritative tool for diagnosing red-green color vision deficiencies. Created by Dr. Shinobu Ishihara in 1917, this test has become the standard method worldwide for assessing color blindness. The 38 plates included in this book are specifically designed to provide a reliable and accurate evaluation of various degrees of color blindness.

Key Features:

38 Plates for Comprehensive Testing:

The book includes a set of 38 uniquely designed plates, each containing a series of colored dots. These dots form numbers or patterns visible only to individuals with normal color vision. For those with color vision deficiencies, the patterns may appear different or be invisible.

The 38-plate version offers an in-depth assessment, making it ideal for clinical settings, schools, and workplaces where precise identification of color vision deficiencies is required.

Test Design and Purpose:

Each plate is meticulously crafted to detect various forms and degrees of red-green color blindness, such as protanopia (red blindness), deuteranopia (green blindness), and their mild variants (protanomaly and deuteranomaly).

The patterns test both the clarity and the extent of the color deficiency, providing a clear understanding of the type and severity of color vision impairment.

Standardized Testing Method:

The Ishihara test is a non-invasive and quick procedure, usually taking about 10-15 minutes. The individual undergoing the test is asked to identify the numbers or patterns within each plate, ensuring a standardized approach.

It is widely used by optometrists, ophthalmologists, and vision screening programs due to its simplicity and accuracy.

Clinical and Practical Applications:

Medical Diagnosis: Essential for diagnosing congenital red-green color blindness in children and adults.

Professional Screening: Valuable for industries where accurate color perception is crucial, such as aviation, maritime navigation, electrical work, and graphic design.

Educational Use: Useful for schools and special education programs to assess students’ visual abilities and provide necessary accommodations for those with color vision deficiencies.

User-Friendly Design:

The book features clear instructions for both administrators and patients, ensuring ease of use. Each plate comes with an answer key to facilitate correct interpretation of results.

Constructed with high-quality, durable materials to withstand repeated use in clinical environments, ensuring longevity and accurate results over time.
