Baby three and a half years old or do not know the color is colorblind

Color blindness refers to the loss of the ability to recognize certain colors. If the baby is colorblind due to genetic, retinopathy and other factors, it can not recognize color phenomena. However, other factors can also cause this situation, such as color weakness, abnormal intellectual development, etc. Therefore, it is not possible to judge whether there is color blindness simply based on not recognizing color.

If parents suspect that their child has color blindness, they can go to the hospital for relevant examinations to make a clear diagnosis, such as false isochromatic examination, color bundle examination, etc.
