Developed by Dr. Shinobu Ishihara, the "Ishihara Color Blindness Tests" have been used for years by ophthalmologists for screening patients for color blindness. This short book consists of a set of colored diagrams with numbers or figures hidden in them. Those with color blindness will not be able to distinguish the number or figure from the surrounding dots. When used properly, these tests can help you determine the type and degree of color blindness. The 24 plate chart aids employers in testing for color blindness. Produced by Western Optahalmics. KEYWORDS: ISHIHARA; VISUAL ACUITY; VISUAL; VISION; VISION TEST; EYE CHART.
