When it comes to reading and many other activities in life, it is important to know how to test your child for color blindness.
Color Blindness in Children Can be Overcome
Color blindness has a profound effect on children, but it need not have a negative impact on their lives. If you suspect your child may have that condition, there are simple tests to find out for sure. Some career choices may be limited as an adult, but most people adjust to it with no difficulty.
Determining the Condition
The first way to tell how to test your child for color blindness is to use the Ishihara Color Test, which has colored plates with squiggly lines and different colored numbers. Children with normal vision can easily read the numbers and see the lines, but children with color blindness can’t. The number of plates the child can distinguish depends on the severity of the condition.
Another way of knowing how to test your child for color blindness is to have your child look – in private – at an image of dots depicting forest animals. Children who have normal vision will be able to easily identify the shapes of the individual animals, but children who are color blind won’t be able to see the shapes. The beauty of this test is that it can be used with very young children who have not learned their numbers or colors yet. Some interesting results were observed.
- Children having normal vision see the deer, the squirrel, the rabbit and the bear. They can’t see the fox.
- Those with red-green color blindness see a cow instead of a deer. Children with a severe form of the condition have trouble seeing the squirrel or the rabbit.
- The condition varies from mild to severe. In general, individuals with this type of color-deficiency can see the fox but not the bear.
Children with red-green color blindness have trouble distinguishing red from green, green from brown, purple from blue and gray from pink. In daily life, a flashing red traffic light looks amber, and a green light looks white. However, most color blind children can tell the difference between the primary colors.
Causes and Coping with Colorblindness
Colorblindness, also called a color vision problem, is usually hereditary. Children who have it lack the proper cone cells in their eye, so they struggle in school when trying to read or differentiate between red, blue and green. It’s permanent, but there are ways of compensating for the condition.
- Wearing colored contacts can help you see more normally by helping distinguish differences between colors.
- Wearing special glasses to reduce brightness can also help. Seeing the difference in colors and hues is easier with less glare.
- Learning to spot clues like location and brightness rather than colors is also an adaptive technique. Paying attention to the order of traffic lights is an example.
Having vision problems is bad for your child’s self-esteem and confidence level. To avoid any stigma, testing by age 3 or 4 is recommended. If you do find any color blindness, telling the teacher as soon as possible increases your child’s chances of success.
As far as what careers will be open to your child, most of them will still be attainable. Color blind adults will have a tough time getting a job requiring them to see colors accurately. Electricians need to see color-coded wires correctly, and cooks and chefs need to tell the color of meat to know if it’s cooked thoroughly. Painters and fashion designers rely on their ability to see variations in color.
Happily, not all aviation-related careers are completely closed off. Some adults with the condition can still become commercial airline pilots, depending on the severity of their condition. Your kids may be inspired to know that NASA Astronaut Roger Crouch, who made two space flights in 1997, is color blind. These are the many reasons that you need to know how to test your child for colorblindess.
Facts and Statistics
Boys are at a greater same risk for red-green color blindness because the gene that leads to this condition is found in the X chromosome. Males have only one X chromosome and females have two. Usually in females the stronger chromosome is dominant, so females are more likely to see colors normally. Genetic makeup leads to some interesting statistics.
- The son of a woman carrying a faulty X chromosome has a 50 percent chance of inheriting the color blindness gene.
- The daughter of that same woman is unlikely to be color blind unless her father is, but she still has a 50 percent chance of carrying the gene.
- Yellow-blue color blindness also exists, but is rare. Only 5 percent of color blind people have this condition.
- The gene for yellow-blue color blindness is located on chromosome 7. A mutation of this gene is what causes the condition.
Famous People Who are Color Blind
Famous people from all walks of life can be affected. Fred Rogers from the children's TV show “Mr. Rogers’ Neighborhood” is red-green color blind, and can’t tell the difference in color between tomato and pea soup. Actor Paul Newman wanted to a Navy pilot, but his color blindness kept him out of the military. Golfer Jack Nicklaus can’t distinguish between a green number and a red number on the leader board.
Don’t despair if you learn your child is color blind. The chances of leading a normal life despite the condition are excellent. The key is understanding how to test your child for color blindness so you can make quick corrections and keep the proper perspective.
