Did you know the Ishihara is functionally obsolete? That means while it does work, it DOES NOT test for acquired color deficiencies. We recommend the Good-Lite HRR Color Test Book, the gold standard for color screening and diagnostics. You can test for Protan, Duetan, and Tritan deficiencies, and diagnose the severity of those deficiencies. Make sure you have the best tools for your practice. Click here for more info. Uses numbers and tracking patterns to test for red and green deficiencies only. Available in 14, 24, or 38 plates. Show more
