1m4 Color charts for Ishihara vision testing

The 1m4 Ishihara color charts come in a practical ring binder containing 35 vision test cards along with answer cards. These cards are used to diagnose red-green color vision deficiencies and help determine the type of visual impairment (deuteranomaly or protanomaly). The color charts feature different colored dots that form specific patterns. Patients with a certain type of color vision deficiency may not be able to recognize some or all of these patterns, which helps in diagnosing color blindness. The convenient ring binder is suitable for pediatric, school, and occupational vision screenings.
