Why do children have red eyes?

It is said that eyes are the windows to the soul, especially children's eyes, which have not yet been tainted by the dust of the world and look crystal clear, like ink-colored crystal. Under normal circumstances, children's eyes are clear, but some children's eyes are often red. Some of them have conjunctival congestion when they cry, some are stimulated by foreign objects, and some are infected with bacteria. So, why do children have red eyes? Is it a disease or a coincidence?

The lips and cheeks of a healthy person are always rosy in color. This is because the lips and cheeks are rich in capillaries. However, the conjunctiva covering the white of our eyes (medically known as the "sclera"), although also with very dense capillaries, appears clean porcelain white, as if there is not a single blood vessel. If you use your fingers to hold open your eyelids and look closely, you will see that there are a few sparsely distributed capillaries on the conjunctiva surrounding the black pupil (cornea), and their number only accounts for about 1% of the entire conjunctival blood vessels. There are two types of eye congestion: superficial and deep. The former is bright red and is called "conjunctival congestion"; the latter is dark red and is called "ciliary congestion". The condition that has both symptoms is called "mixed congestion". These different types of congestion are very meaningful during doctor's examination and diagnosis, and are also one of the important bases for judging the severity of eye disease, but it is difficult for ordinary laymen to distinguish them. Some people believe that the redder the eyes, the more serious the condition. Some people don't care much if they are not jealous. Actually, it is not. For example, acute conjunctivitis has an acute onset and severe congestion, but it is not considered a serious illness. If there are no special circumstances, it generally will not cause major problems and is relatively easy to cure. However, for diseases such as chronic iridocyclitis, scleritis, and glaucoma, the symptoms of congestion are not very obvious, but they are serious eye diseases that cannot be ignored.

Children's physical health requires careful care from parents. Children are at the age when they like to play, so eye safety protection is a very important matter. These protections include not only bacterial protection but also physical protection. Because eyes are more sensitive and easily injured than other organs, parents and friends should protect children's eyes as much as possible. Especially when a child's eyes are red, do not take it lightly and seek timely treatment.
