What is the reason that the eye is white and blue

summary

Changes in diet and living habits, white eyes and blue hair can be seen everywhere in today's society. Of course, you can't see the full picture of normal eyeballs. What we see is just some organizations outside. First of all, the cornea as transparent as glass and the pupil as dark as black may come into view; then there is the light blue or porcelain white sclera (commonly known as the white eye) around the pupil. Just these, there are many diseases can be seen from here. Let's share some experience.

What is the reason that the eye is white and blue

First: the eye is white and blue, which is called blue sclera in medicine. Its appearance is the result of chronic iron deficiency.

Second: the mechanism of its formation is: iron is a very important material in the surface collagen tissue of sclera. Iron deficiency can make sclera thin and can't cover up the dark blue choroid under sclera, and the eye white will appear blue.

Third: it should be porcelain white or light blue. If the color changes and turns yellow, especially when it turns yellow in the sunlight, it is likely to be a sign of liver disease or hemolysis (i.e. massive destruction of red blood cells). It's very interesting that the depth of yellow often represents the severity of jaundice: deep color makes jaundice heavy; light color makes jaundice light. Moreover, the appearance of jaundice on the sclera and yellowing of the ground skin are early, so doctors can find out the problem in advance.

matters needing attention

The white of the eye is purplish red, with a little bulge. At the same time, the eye is painful, which tells people that the sclera is inflamed. If a person with head injury finds that his eyes are covered with blood and are bright red, he should be alert to the possibility of orbital injury or craniocerebral injury. Most of the injuries are serious.
