Eight Kinds of Nutrition That Our Eyes Need
By Tang Qian
Nowadays, people are suffering a lot from declining vision, we overuse our eyes
too much and the nutrition we need are usually not supplemented in time. What
are the nutrients that our eyes feed on? Now let’s have a look at them one by one
(1) Protein is one of the basic elements of visual development. The normal function
of the eyes and updating of eye tissues cannot go without protein. If protein is in
short supply for long, vision loss and all sorts of eye diseases may be induced.
2) Vitamin A plays a very important role in eye metabolism. It is helpful to
maintaining the normal structure and physiological function of cells. At the same
time, it is one of the main elements to synthesize visual phytochrome. Lack of
vitamin A can lead to retinal rhodopsin insufficiency and the dark adaptation ability
of the eyes will drop.
(3) Vitamin B can guarantee the normal metabolism of the retina and cornea and
provide the visual nerves with nutrients. If the human body doesn’t absorb sufficient
amount of vitamin B, the eyes will be prone to fatigue, tears, redness and
muscle spasm etc
(4) Vitamin C is a very important substance in cell synthesis. Lack of vitamin C
may induce corneal opacity and corneal ulcer, and further lead to corneal puncture.
Optic nerve and retinal inflammation may also occur.
(5) Zinc plays an important role in the human body. It is the activity center of a
variety of enzymes. As the intraocular metabolism is extraordinarily active, many
metabolic enzymes are metal enzymes related to zinc. Therefore, zinc deficiency
can lead to reduction of aqueous humor and oxidation resistance in eye tissues,
causing retinopathy and optic atrophy. Researches have shown that the serum zinc
content of myopia patients is significantly lower than that of the normal people.
So supplementing zinc can help improve the vision of myopia patients.
In addition, tests show that the zinc content in the hair of amblyopia patients is
also very little. Therefore, zinc insufficiency may be relevant to amblyopia formation.
(6) Copper is one of the important trace elements for the human body which plays
an important role in the formation of pigment. Lack of copper can cause a variety
of diseases. Metabolic abnormalities of copper can lead to retinal pigment
deformation and affect our vision, causing damages to the lema. Researches show
that the serum copper and urine copper contains of myopia patients are obviously
lower than normal.
(7) Selenium is the essential nutrients to maintain the vitality of the human body
and at the same time, the activity center of magnesia resistance. It can delay cell
aging and adjust the absorption and consumption of vitamin A, vitamin C, vitamin E
and vitamin K. In the metabolic process, selenium deficiency can lead to
cataract and myopia.
(8) Women who like to eat food with high sugar contain are more likely to
suffer from ocular axial elongation, which has facilitated myopia development.
