Well, for some people, yellow eye can be possible. And for the causes, first you need to know something about it. Generally speaking, if your eyes take on a yellow tinge, the reason may be jaundice. There is a substance called bilirubin, which remains after old red blood cells are disposed of, is responsible for the yellow pigment. Of course, in common, if too much bilirubin accumulates in the body, jaundice can result. And then, yellow eyes can occur too. That is why you get yellow eyes. In detail, yellow eyes can be caused by many reasons, such as iron deficiency, smoking and so on. If you suffer yellow eyes because of iron deficiency, just eat foods such as beef, liver, chicken, green leafy vegetables and beans to increase your iron levels. Anyway, just be careful about it.
