Color blindness: how color blindness is detected and who it affects most

Color blindness is a rare condition called color blindness which does not allow you to see colors normally.

There are several degrees of color blindness. While some have difficulty identifying certain colors in low light, others cannot distinguish certain colors in any type of light.

Most cases of color blindness are due to a genetic problem It tends to affect men more frequently. It is estimated that around one in 10 men suffer from it.

How can color blindness be detected?

According to the American Academy of Ophthalmology, the color blindness can be detected by a simple test, known as Ishihara test. This test is performed using a series of images with numbers surrounded by colored dots.

The numbers are a different color than the rest of the background. If you can’t identify the numbers, that’s most likely the case colour blind. It should be noted that if the test result is positive there is no reason to panic.

Although there is currently no treatment, there are special glasses and contact lenses that can help people identify similar colors to each other.

Why does color blindness occur?

The American National Eye Institute states that in most cases the color blindness has a genetic origin and is transmitted from parents to children via the X chromosome.

Those men who inherit a X chromosome with the faulty gene will suffer from this condition. On the other hand, color blindness will only affect women if both parents are carriers of the gene. This is why cases in them are less frequent.

Furthermore. He Color blindness can be caused by diseases or injuries. Some common causes are:

• Eye diseases, such as glaucoma or age-related macular degeneration.
• Diseases of the brain and nervous system, such as Alzheimer’s or multiple sclerosis.
