Matronix Color Blindness Test Chart - 38 Plates

The Matronix Color Blindness Test Chart - 38 Plates is a comprehensive pseudoisochromatic screening tool designed for the detection of color vision deficiencies. Based on the internationally recognized Ishihara methodology, this 38-plate edition facilitates detailed assessment of red-green color vision anomalies, including protan (red deficiency) and deutan (green deficiency) defects. It is widely utilized in ophthalmology clinics, optometry practices, occupational health screenings, schools, and government medical examinations for diagnosing both congenital and acquired color vision defects.

Each of the 38 plates consists of a solid circle of carefully calibrated colored dots, arranged to form numbers or patterns. These pseudoisochromatic plates are designed such that figures are clearly visible to individuals with normal color vision, but difficult or impossible for those with red-green color vision deficiency to perceive. The chart includes various plate types such as demonstration, transformation, vanishing, hidden digit, and diagnostic plates, which aid in the differentiation and classification of color vision defects.

The high-quality printing of the Matronix Color Blindness Test Chart ensures accurate color contrast and consistent diagnostic reliability when administered under standardized daylight illumination conditions. Its standardized testing format makes it suitable for diverse clinical, academic, and occupational screening applications, including driver’s license color vision testing.
