Colour Blindness Test Book
Color deficiency education is so important because people often overlook how much the inability to see certain colors can change a person’s life. It affects everything from what jobs a color-deficient person can do to small choices like what that person would want to eat. Color blindness can also happen because of damage to your eye or your brain. And color vision may get worse as you get older — often because of cataracts (cloudy areas in the lens of the eye).
If you have color blindness, it means you see colors differently than most people. Most of the time, color blindness makes it hard to tell the difference between certain colors. Usually, color blindness runs in families. There’s no cure, but special glasses and contact lenses can help.

The main symptom of color blindness is not seeing colors the way most people do. If you’re color blind, you may have trouble seeing:
- The difference between colors
- How bright colors are
- Different shades of colors
Symptoms of color blindness are often so mild that you may not notice them. And since we get used to the way we see colors, many people with color blindness don’t know they have it.
People with very serious cases of color blindness might have other symptoms, too — like quick side-to-side eye movements (nystagmus) or sensitivity to light.
