Color vision test
open-in-new
<p>A color vision test is used for measuring <a href="/facts/Color_vision/j3ou3Izz">color vision</a> against a standard. These tests are most often used to diagnose <a href="/facts/Color_vision_deficiencies/02Taxf5C">color vision deficiencies</a> ("CVD"; color blindness<i>), though several of the standards are designed to categorize normal color vision into sub-levels. With the large prevalence of color vision deficiencies (8% of males) and the <a href="/facts/Color_blindness/02Taxf5C">wide range of professions that restrict hiring the colorblind</a> for safety or aesthetic reasons, clinical color vision standards must be designed to be fast and simple to implement. Color vision standards for academic use trade speed and simplicity for accuracy and precision.</i> </p>
