Extended data:

1, white and blue eyes are medically called blue sclera. This sign is mostly caused by chronic iron deficiency. Iron is a very important substance in the collagen tissue on the sclera surface. Iron deficiency can make the sclera thin, and when the dark blue choroid under the sclera can't cover it, the whites of the eyes will appear blue.

2, often eat food that is good for the eyes, which is conducive to caring for eye health. For example, deep-sea fish contains a lot of DHA, which can make the retina of eyes develop healthily and prevent diseases and cataracts. Animal liver, blueberries and nuts can resist aging, improve eyesight, protect eyes and relieve optic nerve fatigue.

3. Lutein and zeaxanthin are the main components of vegetable pigments, fruits, flowers and other plant pigments, and they are also the main pigments in the macular area of human retina. Human eyes contain a lot of lutein, which is an element that the human body cannot produce and must be supplemented by lutein intake. Without this element, the eyes would be blind.
