First, the signal that the eyes of the human body are stimulated. Under normal circumstances, the cornea of our body has no blood vessels. If the eyes are stimulated, the blood vessels will slowly appear on the eye membrane. Therefore, if we usually see red blood on our eyes, it is because the eyes are stimulated. Children's eyes are black and white. That's because children's eyes don't have too much work, and they don't read books and watch computers frequently or use their eyes excessively. But as we get older, the frequency of using our eyes will become higher and higher, and more and more impurities will come into contact with the outside world. All kinds of bacteria and viruses or the stimulation of air pollution will lead to blood vessels coming out of our eyes.
Second, what is the situation of the child's white eyes with red blood? When we find that the red blood in the child's eyes is often because the child has weak lungs in his body, it may be that the previous cold has not been completely cured, and some pathogens will remain in the lungs, or it may be caused by other circumstances, such as bad mood or poor sleep quality. If the bloodshot blood in the child's eyes has penetrated into the pupil, it means that the pathogens have penetrated into the child's body and may continue for a while. If the child's white eyes are found to be yellowed, it may be caused by food accumulation or phlegm accumulation in the child's body. It is best to take the child to see a doctor.
To sum up, we should tell our children not to overdo it when using their eyes at ordinary times. We should create some good environment for their eyes, look more and do more eye exercises in the distance.
