What is Protanopia?
Protanopia is a type of red-green color blindness where the red-sensitive cone cells in the eye are absent or non-functional. People with protanopia have difficulty distinguishing between red and green colors, and reds may appear darker or black.
Common Challenges
- Red and green look similar or identical
- Red appears darker than normal
- Difficulty with traffic lights and warning indicators
- Brown, green, and red may be confused
- Purple can look blue
