Color blindness tests, also known as color vision tests, are used to assess your ability to distinguish between different colors. These tests are particularly important for professions where accurate color perception is crucial, such as graphic design, aviation, and electrical work.
There are two main types of color blindness tests:
- Pseudoisochromatic plates: These are the most common type of color blindness test. They consist of plates with dots of different colors arranged in a pattern. A number or letter is formed by dots of a different color, which people with normal color vision can easily see. However, people with certain types of color blindness may not be able to see the number or letter.
- Lantern tests: These tests use colored lights or filters to assess color vision. People with normal color vision will see the lights or filters as one color, while people with certain types of color blindness may see them as a different color.

Brief overview of color blindness and its types
Color blindness, or color vision deficiency, is a condition where individuals experience altered color perception compared to those with normal color vision. This happens due to differences in how the cones, light-sensitive cells in the retina, function.
There are three main types of color blindness, each affecting the perception of a specific primary color:
- Red-green color blindness: This is the most common type, affecting around 8% of men and 0.5% of women. Individuals struggle to distinguish between reds, greens, browns, and oranges.
- Blue-yellow color blindness: This is much rarer, affecting about 0.01% of the population. It makes it difficult to differentiate between blues, yellows, and purples.
- Complete color blindness: This is extremely rare, affecting about 0.00035% of the population. Individuals with this condition see in shades of gray, with no color perception at all.
Severity within each type of color blindness can also vary, with some individuals experiencing milder difficulties and others having almost complete absence of color perception.
Causes of color blindness are typically inherited, with genes playing a significant role. It can also be acquired through injury, disease, or certain medications.
While color blindness affects daily life in some ways, such as difficulty with traffic lights or color-coded information, most individuals adapt and manage well. Many resources and supportive technologies are available to assist people with color vision deficiency.
