1 Answer:

Hello Haneefa,

Color blindness is a state in which there is interference to see and distinguish color gradations. This condition is inherited from parents and is usually more common in men. A person who is color blind sometimes does not realize that he is color blind before examining the color blind test. The most common type of color blindness is red-green color blindness. Patients have difficulty distinguishing the two colors, as well as the derivative and gradation of the color. Patients may have difficulty differentiating the colors of traffic lights, distinguishing colorful drugs and drug labels, choosing colors such as the color of cloth when working as a designer, and so on.

The most often done color blind examination is to use the Ishihara test (reading numbers or drawing shapes, which are a combination of several colored dots). The results were generally the same / constant did not change for the same patient. The validity period is actually not there, but generally a company / institution requests the results of a medical test (including color blindness test) the last 6 months. When it's past that time then most will ask to double check.

Thus the explanation from me, may be useful.
