Should Adoption Be Colour Blind?

Children with an ethnic background (average) were taken three times longer than children with white background. This is because my family does not want only white children. No, this is totally wrong. Social workers prevent white families and couples from adopting different ethnic children. This is because these families can not take care of children. Again, this is wrong. Social workers wait for "perfect match" (such as matching between a black child and a black family), even if the child has never been adopted.

There are many kinds of color blind with varying degrees of severity. People with color blindness can only see black and white, this is a universal myth. This may be true, but monochromaticity (also known as full-color blindness) is extremely rare, with an estimated 33,000 affected. This severe visual impairment only makes it possible for individuals to see in grayscale. An important element to remember is that it is not difficult for most people with color vision distinction to distinguish between different colors, which will explain the difference in brightness level between hue and similar colors.

Color vision disorder that distinguishes color vision abnormality mainly affects men. Color blindness is caused by defects in the retina or other nerve parts of the eye. Partial color vision abnormalities known as dichroism usually involve being indistinguishable from red and green, or perceived red or green, and rarely confusion can be accompanied by blue or yellow. Dichroism is the most common form of color vision abnormality that affects about 7% of men, less than 1% of women. Dichroism was identified as a gender-related genetic feature (Figure 1).

The British 8% male population and 4.5% population are color vision abnormalities, with an estimated 250 million people worldwide. The majority of people with color vision disorder inherit their state from their mothers. Mothers are usually "carriers", not color vision abnormalities. Some people suffer from chronic diseases such as diabetes, multiple sclerosis, some liver diseases, almost all eye diseases. For details on how to obtain conditions, please click.

1948, H. L. de Vries is studying the eye of a color vision male. He assumed that male and daughter of a color vision males will have four color cones instead of three because color vision abnormality occurs within the family. In addition to three normal conical shapes, they have male abnormal cones in their families. The idea of ​​De Vries is that there are four cones that allow them to see more colors than most people, which is why their test results are abnormal. He advocated the idea of ​​four cones at the end of the paper and did not mention it to any of the next research.
