is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions. Color blindness affects a significant percentage of the population. There is no actual blindness but there is a deficiency of color vision.
Common symptoms of color blindness include:
• Difficulty distinguishing between colors
• Inability to see shades or tones of the same color
• Rapid eye movement (in rare cases)
There are many tests available to measure color vision defects but the most common is the Ishihara Plate test. This can test for red/green color blindness but not blue color blindness.
There is no known treatment for color blindness. Fortunately, the vision of most color-blind people is normal in all other respects and certain adaptation methods are all that is required.
You can find ways to help make up for a color vision problem, such as:
• Wearing colored contact lenses. These may help you see differences between colors. But these lenses don't provide normal color vision and can distort objects.
• Wearing glasses that block glare. People with severe color vision problems can see differences between colors better when there is less glare and brightness.
• Learning to look for cues like brightness or location, rather than colors. For example, you can learn the order of the three colored lights on a traffic signal.
