Frequently Asked Questions
Color blindness (color vision deficiency) affects how you perceive certain colors. The most common type is red-green color blindness, affecting about 8% of men and 0.5% of women. Other types include blue-yellow blindness and complete color blindness (rare). Most color blind people see colors, just differently.
The Ishihara test uses circular plates with colored dots forming numbers or patterns. People with normal color vision see one number, while those with color deficiencies see a different number or none at all. Our digital version includes standard Ishihara plates plus additional tests for comprehensive screening.
Color blindness is usually genetic and currently has no cure. However, special glasses and contact lenses can help some people distinguish colors better. Understanding your specific type of color vision deficiency helps you adapt and use tools designed for accessibility.
If this test suggests color vision deficiency, consult an eye care professional for a comprehensive evaluation. They can confirm the diagnosis, identify the specific type, and discuss how it might affect your daily life or career choices. Some professions require normal color vision.
