The human eye has eighteen times more rods than cones. But the cones are what give us fine detail and color. They work best in bright daylight. All types of color blindness have to do with diminished or absent functionality in the cones. The human eye contains three different types of cones. S-cones short-wavelength absorbing cones help us see blue, M-cones medium-wavelength absorbing cones reveal green and L-cones long-wavelength cones interpret red light.
The absence of any of the three types of cones is what accounts for different types of color blindness. With just those three light sensitivities, we can see literally thousands of colors. Individuals who have all three types of cones working at full capacity are called trichromats tri meaning three and chroma being the Greek word for color. Likewise, normal vision can be referred to as trichromacy. The different types of color blindness are generally divided by whether the vision defect is inherited or acquired.
Inherited types of color blindness are grouped by red-green and blue-yellow, along with the more rare monochromacy total color blindness. Similar distinctions exist among the acquired forms of color blindness. Though the causes may be different, the resulting symptoms color blindness of some degree of severity are ultimately caused by deficiencies in the cone photoreceptors.
Most people who have trouble seeing various spectrums of light have what is called inherited color blindness. The genes that code for correct cone function, which are passed down from their parents, have an error.
This is why color blindness tends to run in families. The most common types of color blindness in humans fall under the heading of anomalous trichromacy.
People who are color blind can only see certain colors, depending on which type of color blindness they have. The types of red-green color blindness fall into four different categories. Protanomaly aka red-weak — Individuals have red cones and can usually see some shades of red. Deuteranomaly aka green-weak — Individuals have green cones and can usually see some shades of green. Ultimately, the different types of red-green color blindness all result in the individual seeing a world the rest of us would describe as murky green with hints of blue and yellow.
Browns, oranges and reds are easily confused, and pale shades in general are difficult to distinguish. Blue-yellow color blindness is less common. The two types of color blindness in this category both make it difficult to tell the difference between blue and green, as well as yellow and red.
Do you need to pass a color vision test for your job or licensing? Are you concerned about your results? Did you struggle to see several of the numbers? Did you find yourself guessing instead of confidently entering the answers? If the test shows that you may be color blind, and you feel that color blindness is affecting your everyday life, then there is good news for you. Color blindness treatment is available to help you see the full range of colors that other people see and can guarantee the passing of the Ishihara Color Plate Test!
This system has helped thousands of people just like you overcome color blindness and the challenges it can cause. Green color blind people see a 4. If you are color blind, you do not see a number. If you are totally color blind, you do not see a number. If you are red color blind, you see a 6. If you are green color blind, you see a 2. There is currently no treatment for inherited color blindness.
