Most of the time, color blindness makes it hard to tell the difference between certain colors. Usually, color blindness runs in families.

Try the following tips to help you work around your color blindness.Memorize the order of colored objects. If it's important to know individual colors, such as with traffic lights, memorize the order of the colors.Label colored items that you want to match with other items.Use technology.
99% of color-blind males and females are color blind as a result of defective genetics on the X-chromosome. To cure inherited color blindness would require some form of gene repair to the damaged chromosome.
People who are color blind see normally in other ways and can do normal things, such as drive. They just learn to respond to the way traffic signals light up, knowing that the red light is generally on top and green is on the bottom.
Trouble Seeing Different Shades
Similarly, if different shades of colors do not stand out to you, you may be color blind. Reds, greens, blues, and yellows are the most common colors that people who are colorblind have trouble identifying in different shades.
Most color blindness is permanent. Some conditions can lead to temporary color blindness. During certain kinds of migraine, some people are unable to tell the difference between certain colors. There is no treatment cure for permanent color blindness.
The Ishihara test includes 38 circular plates having printed digits on which are created by unique random dots in more than one color. The plate will be shown in the test to the person and asked which number will be seen. If a person makes some mistakes during the test, they are diagnosed with color blindness.
Color blindness is a lifelong condition. Most people are able to adjust to it.
There are different types of colour blindness and in extremely rare cases people are unable to see any colour at all, but most colour blind people are unable to fully 'see' red, green or blue light.
Achromatopsia is also known as “complete color blindness” and is the only type that fully lives up to the term “color blind”. It is extremely rare, however, those who have achromatopsia only see the world in shades of grey, black and white.
If you have color blindness due to a health condition, your symptoms may get worse slowly over time. They may also affect one eye but not the other. You may find it very hard to pick out dark colors, especially blues.
Color blindness is an often misunderstood condition. Many assume because of its name that “color blind” means a person can only see in black and white. In actuality, the vast majority of people with color blindness do see color, but they see a much narrower range of color.
Question: Can color blindness come and go Answer: There is a condition called transient achromatopsia that causes a temporary loss of color vision.
Rod monochromacy: Also known as achromatopsia, it's the most severe form of color blindness. None of your cone cells have photopigments that work. As a result, the world appears to you in black, white, and gray. Bright light may hurt your eyes, and you may have uncontrollable eye movement (nystagmus).
The types of red-green color blindness fall into four different categories. Protanopia (aka red-blind) – Individuals have no red cones. Protanomaly (aka red-weak) – Individuals have red cones and can usually see some shades of red. Deuteranopia (aka green-blind) – Individuals have no green cones.
Ninety percent of individuals who are identified as legally blind have some useful vision or light perception. Total darkness is rare. Color blindness and visual processing disorders are other types of visual disabilities.
Rod monochromacy (Achromatopsia)
This is the rarest and most severe form of color blindness in which there are no functional cone cells with working photopigments. People with rod monochromacy can only see black, white, and gray.
Intelligence is linked to the ability to ignore distractions, and colors can affect our concentration, while people with color deficiency have fewer problems with colors and get distracted less than other people. It helps them to focus on specific tasks, without distractions, which is a crucial part of any success.
Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.
Currently there is no cure for color blindness that is present from birth. If you have this condition, you may benefit from special color glasses or tinted contact lenses. They may help you tell the difference between some shades. But they don't give you normal color vision.
Mouse over this standard colorwheel to see it as a colorblind person might see it. Color vision deficient people have a tendency to better night vision and, in some situations, they can perceive variations in luminosity that color-sighted people could not.
Color blindness is typically an inherited genetic disorder.
Colorblindness will most likely be considered a disability under Americans with Disabilities Act (“ADA”). The ADA considers a condition to be a disability if it substantially limits a major life activity, such as seeing, learning, or working.
Age – in people over 60 years physical changes can occur are likely to affect a person's ability to perceive colours and research shows colour vision declines more rapidly after age 70.
Females inherit one X chromosome from each parent; hence they can be either homozygous or heterozygous. A color-blind girl is born only when her father is color blind, and her mother is a carrier. If the maternal grandfather is color blind, the mother will be a carrier.
