What's the difference between color blindness and color weakness? Can color blindness be inherited?

For color blindness, we are not new, because in our side, there are always some such people. In their eyes, the color of the world may be reversed. So what's the difference between color blindness and color weakness? Let's learn about it with Xiaobian.

In fact, there are not only color blind people, but also color weak people. Color blindness, like color weakness, is a manifestation of abnormal color perception, which is usually related to genetic diseases, but less caused by acquired causes. Although both color blindness and color weakness are manifestations of abnormal color perception, they are essentially different:

1、 Color blindness is the loss of the ability to distinguish colors. According to the theory of three primary colors, those who can't distinguish red are red blind, those who can't distinguish green are green blind, those who can't distinguish blue are blue blind, and those who can't recognize all three colors are all color blind.

2、 Weak color refers to the weakening of the ability to distinguish colors. That is to say, people with weak color can recognize all colors, but they are slow to recognize them, or they can only recognize them after repeated consideration.

3、 Color blindness is completely unable to distinguish some colors, while color weakness can distinguish colors, but the discrimination ability is worse than that of normal people.

Although there is a difference between color blindness and color weakness, there is also a certain relationship between them. Generally, there are different degrees of color weakness. Severe color weakness patients are equivalent to slight color blindness patients, and their ability to distinguish colors is very poor. But the light color weak patient, mostly does not need the treatment, has the feeling to the color, only distinguishes when is quite difficult. The same as color blindness, there are more male patients than female patients.

There is no way to treat color blindness and color weakness caused by hereditary diseases. But for some acquired factors caused by color vision abnormalities, it can be treated, especially for color weak diseases, we should actively need medical treatment.
