Most people with CVD are not aware of their condition because they have adapted to seeing the world differently since birth. The Ishihara test, developed by Dr. Shinobu Ishihara in 1917, remains one of the most widely used and trusted methods for screening color vision deficiencies. It uses specially designed plates with colored dots that form numbers visible to people with normal color vision but difficult or impossible to see for those with color vision deficiencies. Early detection of color vision deficiency is important for career planning, safety awareness, and understanding how you perceive the world around you. ▸ IMPORTANT DISCLAIMER This app is a screening tool designed for educational and informational purposes only.
