People with color visual impairment have difficulty distinguishing and distinguishing certain colors.
Although complete color blindness (not being able to see color) is very rare, it is sometimes referred to as “color blindness”.
Color vision deficiency is usually inherited (inherited) from the parents to the baby and occurs from birth, but can sometimes develop later in life.
Most people can adjust to their color vision deficiency, and this is rarely a sign of anything serious.
Types and symptoms of color vision impairment
Most people with color vision disorders have difficulty distinguishing between shades of red, yellow, and green.
This is known as “red-green” color vision deficiency. This is a common problem that affects about 1 in 12 men and 1 in 200 women.
Someone with this type of color vision loss can:
It is difficult to distinguish between red, orange, yellow, brown and green tones
Perceive these colors as duller than they would appear to someone with normal eyesight
I have a problem with differentiating between shades of purple
Mix red and black
On rare occasions, some people have problems with blues, greens, and yellows. This is known as “blue-yellow” color visual impairment.
Color vision impairment tests
If you suspect that you or your child may have color vision problems, ask your optician to gray color blind test your color vision, especially if it has started suddenly or worsens.
Color vision gray color blind tests are usually not part of the Covisn eye exam routine, but you can ask for them.
The two most important tests used to diagnose color vision deficiency are:
Covisn test in which you have to identify the numbers in the pictures with dots of different colors
A color scheme in which colored objects should be arranged according to their different shades
There are many tests online that use similar techniques that can help you identify a potential problem. However, if you have any concerns about your color vision, it is best to get a proper test from your optician.
Problems for people with color vision disorders
Color blindness is usually nothing to worry about.
Most people get used to it over time, it usually doesn’t get worse and it’s rarely a sign of something serious.
But sometimes problems can arise like:
Difficulty in school using colors as a study aid
Food-related problems such as determining whether the meat is cooked through or the fruit is ripe
Mixing drugs if not clearly labeled
Problem with identifying security warnings or signs
Somewhat limited career options – some professions such as pilots, train drivers, electricians, and air traffic controllers may require accurate color recognition
Overall, many people with color vision deficiency have little or no difficulty. You can do most normal activities, including driving a car.
Treatment and living with color vision deficiency
There is currently no cure for hereditary color vision deficiency, although most people can get used to it over time.
Let your child’s school know if they have difficulty seeing color so that the study materials can be adjusted accordingly
Ask friends or family for help – they will help you choose the right clothes, for example, and make sure the food is safe.
Install quality lighting in your home that will help you distinguish between colors
Use technology – Computers and other electronic devices often have settings that you can change to make them easier to use, and there are many cell phone applications that can help you define colors.
Try special tinted glasses – they are worn on one or both eyes to make it easier to distinguish certain colors, although they may only appear to work on certain people

If your color vision deficiency is caused by a medical condition or medication, treating the underlying cause or using a different medication may improve symptoms.
The causes of color vision disorders
In the vast majority of cases, color vision disorders are caused by a genetic defect that is passed on from the parents to the child.
This is because some color-sensitive cells in the eyes called suppositories are missing or not working properly.
